9. ARGUMENTS IN SUPPORT OF THE NOMINATION ofDr. Lot Shafai for the Booker Gold Medal:Or. Lot Shafai, over a 40 year career, has made a number of pioneering contributions to

telecommunications and related disciplines. Early in his career his work resulted in the design of thefirst generation satellite picoterminal for Canadian Hermes Satellite (see figure). Dr. Shafai'sinnovations in high efficiency feed design, and feed mounted receivers enhanced the antenna gain

and signal to noise ratio sufficiently to shrink the terminal size, for the first timebelow 2ft, ushering in a new era in satellite communications in the form of DirectBroadcast Satellite (DBS). It was used in 1977, in Peru, to broadcast "theCanadian Stanley Cup, final hockey game", live from Montreal, the first everdemonstration of an international OBS application. This terminal won "thePremier Award" for industrial design innovation in 1978. Later, Dr. Shafai also

designed the next generation picoterminals for European Space Agency, at 20/30 GHz, forbroad band satellite communications, winning two awards, "the Engineering Achievement Award",and "the Innovation of the Year Award". In addition, he has assisted his students to transform theirresearch results into pioneering industrial products. One of his students, while in the M.Sc. program,incorporated "Broadband Network Inc. ", to commercialize the first 30 GHz terrestrial link, and soldit three years later for $596M to Nortel Networks. Two other students (M.Sc. and Ph.D),incorporated Spectraworks to design and market a secure 20/30 broadband satellite link and sold ittwo years later for over $1OOM to Norsat International. Many other telecom companies started byhis students and their research, such as "NTG Clarity Network Inc. ", "IMT", and "Novra" areprospering and contributing to Canad ian and global business and connectivity.

Or. Shafai's contributions within the past six years, are even more significant. Two of whichinclude "development of low-loss engineered conductors", and "virtual antenna arrays usingreflectors". Since the invention of rad io by Marconi the communication systems and antennas havesuffered from the resistive loss of conductors, which limit their performance at microwavefrequencies and beyond, especially when miniaturized. The problem is even more severe atmillimetre wave (MMW) and terahertz (THz) bands. To solve these problems, Dr. Shafai hasdeveloped, for the first time, "Low-loss Engineered Conductors", which dramatically reduce theresistive losses of RF components and miniaturized antennas. The implications of this invention areenormous. Conductor losses no longer will limit antenna miniaturization, and RF componentefficiency. In addition, low-loss RF technology can now be extended into MMW and THz bands.

Or. Lot Shafai's virtual antenna array concept transforms a single reflector antenna into anarray, without adding new hardware. While a single antenna suffers from high noise and the lack ofsignal processing capability, the virtual array, so generated, eliminates both problems. It providesnoise cancelation and full signal processing capability for the reflector antenna, without increasingits size, cost and complexity. A real break though in RF engineering, with a real potential for aprofound impact in communication systems, remote sensing, imaging and radio astronomy.

His other innovations include microwave detection and disabling of land minds for UN peacekeeping forces and modelling of the arctic sea ice for investigation of global warming.

Or. Shafai's early research on satellite picoterminal enabled DBS technology, and broughtsatellite communication to small business and every household. His subsequent research on 30 GHzlinks resulted in wideband terrestrial and satellite systems that transformed Canadiancommunication technology, and improved worldwide connectivity. His recent research on low-lossconductors and virtual arrays will revolutionize the communication technology, and enable efficienthardware designs for MMW and THz bands. Dr. Lot Shafai is an ideal candidate for URSI BookerGold Medal.

RE: Nomination of Dr. Lotfollah Shafai for the URSI - Booker Gold Medal

Dear Selection Comm ittee:

On behalf of the University of Manitoba, I am pleased to provide this letter of support for Dr.Lotfollah Shafai, P.Eng., for the prestigious URSI - Booker Gold Medal. Dr. Shafai joined theDepartment of Electrical and Computer Engineering at the University of Manitoba in 1970 andattained the rank of Professor in 1979. From 1989 to 1994, Or. Shafai held the position of IndustrialResearch Chair in Applied Electromagnetics of the Natural Sciences and Engineering ResearchCouncil (NSERC). Since 2001, he has been a Canada Research Chair in Applied Electromagnetics.

Dr. Shafai is one of the world's most innovative and outstanding antenna researchers and is,without doubt, Canada's leading expert in the field of applied electromagnetics and radiating systems.His work has led to new developments in antennas that are widely used by industries concerned withbroadband wireless and satellite communications. He pioneered the development of high performanceand miniaturized reflector antennas, and his research findings have been implemented in householdsatellite TV antennas throughout North America, Europe and the Far East. He has contributed to 17books, written over 915 refereed publications (289 papers in refereed journals and 628 papers inreferred conference proceedings) and holds 13 patents; remarkably, he is still at the peak of his career.

Dr. Shafai has received numerous national and international awards and honours from a varietyof scholarly and professional associations. He is a fellow of the Institute of Electrical and ElectronicsEngineers (IEEE), a fellow the Royal Society of Canada, a Distinguished Professor of Electrical andComputer Engineering, a Fellow of the Canadian Academy of Engineers, and a Canada ResearchChair in Applied Electromagnetics. He was awarded the IEEE Antennas and Propagation Society'sChen-To Tai Distinguished Educator Award, quoted from the award website for his "outstandingcontributions to antenna teaching and research by developing curriculum, numerical techniques,establishing link between industry and university and its impact on students worldwide." In 2011 hereceived the Canada Council for the Arts' Killam Prize in Engineering, the most prestigious award in

umanitoba.ca/research

Canada. Most recently, he received the IEEE Antennas and Propagation Society's John KrausAntenna Award.

To enhance contact between Academ ia and industry, Dr. Shafai was a major player inestablishing The Institute for Technology Development. To promote national and internationaltechnical and scientific exchange, Dr. Shafai established ANTEM, the Symposium on AntennaTechnology and Applied Electromagnetics in 1986. Now held every two years, it is the premierCanadian conference on Telecommunications, Antennas and Microwaves, attracting manyinternational participants, and last year was held in Toulouse, France. His early research contributionsresulted in satellite terminal miniaturization for Hermes Satellite. This work, for the first time,introduced computer aided design (CAD) concept to reflector antenna design and subsequently wasadopted internationally. It formed the basis of current household satellite terminals.

When television journalists broadcast live from war disaster zones or inside hurricanes, manyuse satellite-phone systems with compact antennas to send live images and reports back to the newsdesk. This technology was developed with sophisticated equipment unique in Canada complementedby a highly capable staff in the Applied Electromagnetics Laboratory. Dr. Shafai established (andcurrently directs) this world-class laboratory which is at the frontier of research and development ofcommunications technology and remote sensing, helping Canada lead the world in this field.Technologies that benefit from his research include wireless and satellite communications, remotesensing, radar metrology, radio astronomy, medical diagnostics, and most recently electromagneticmapping of Arctic sea ice.

Or. Shafai is currently supervising 5 Ph.D. students, 3 M.Sc. students and 2 Post-DoctoralFellows in a realm of exciting projects. Many of Or. Shafai's graduates (81 total since 1973: 41 M.Sc.and 40 Ph.O. students) have become leaders in their fields, both nationally and internationally. Notonly has he helped launch the careers of numerous academic researchers, he has mentored and helpedhis graduates develop entrepreneurial skills, which in turn, has generated billions of dollars ofeconomic activity. For example, "Broadband Network Inc." was started by one of his M.Sc. students todesign and supply wireless links and was sold after three years to a major Canadian Electronicscompany for $596M. "Spectraworks" which was started by two of his students (M.Sc. and Ph.D.) todesign and supply broadband satellite links was sold after two years for over $100M. Other majortechnology companies started by his students (and which are prospering) include "NTG ClarityNetwork Inc.," InfoMagnetics Technologies Corporation," Nova Technologies," and "Persentech."

In summary, Or. Lot Shafai is the most successful researcher in Canada in the field of appliedelectromagnetics. His creativity, intellectual leadership and sustained research excellence make himthe ideal recipient of the URSI - Booker Gold Medal.

Yours sincerely,

Oigvir S. Jayas, Ph.D., P.Eng., P.Ag., FRSCVice-President (Research and International) and Distinguished Professor

Dear Selection Committee,

It is a real pleasure to provide this letter of support for the nomination of Dr. Lot Shafai for the Award of the Booker Gold Medal. Over the 43 years of his career in telecommunications and through his research in antenna systems and electromagnetics, he has continuously pioneered novel concepts and technologies making key breakthroughs in telecommunications. While his research is grounded in abstract mathematical equations, radio frequencies and state-of-the-art hardware, many of his contributions to the telecommunication domain have been driven by the needs of the people; for instance, the need for smaller telecommunication devices that have better capabilities and performances.

In particular, Dr Lot Shafai was the first to reduce the size of a satellite ground terminal antenna below 2 ft (60cm), which enabled in 1977 the implementation of Direct Broadcast Satellite technology in using a terminal smaller than a TV. For the story, he designed the smallest reflector using mathematical equations and finalized the prototype during a test using his wedding ring. The usefulness of his technology was clearly demonstrated with the first ever live satellite broadcasting in Peru of the Stanley Cup final hockey game taking place in Montréal, Canada. Further research on this technology culminated in the innovative design of a 1ft (30cm) dual-band antenna for picoterminals developed by the European Space Agency for two-way communications in 20/30GHz bands. More recently Dr. Lot Shafai introduced the virtual array concept, where a single recflector antenna may be transformed into two or more reflector antennas simply by using the multi-mode behaviour of the antenna with signal processing techniques. This concept can easily be extended to other types of antennas and impacts a broad range of applications in telecommunications, remote sensing and radio-astronomy domains in providing additional capabilities to the terminal or in drastically reducing their size. Attempting to push further the boundaries for system improvement and miniaturization, Dr Lot Shafai recently developed the innovative concept of “low loss engineered conductors” to considerably reduce metallic losses. This breakthrough is a significant achievement providing major improvement in performance and efficiency of components such as filters, amplifiers and antennas for applications at microwave to Terahertz frequencies.

While contributing with high efficiency to advances in radio sciences, Dr. Lot Shafai is eager to disseminate his knowledge to students, helping and encouraging them to commercialize the novel technologies. Several of his students founded numerous companies bringing these innovative concepts to commercial products. In particular, one of his student founded Broadband Network Incorporated, to design and supply the first 30GHz terrestrial link. Two other students created Spectraworks to design and supply secure broadband 20/30GHz satellite links. Major telecommunication companies purchased both companies after only few years for several


hundred million dollars. Other companies in the telecommunication sector that were created by his students are still prosperous today. In his desire to promote radio-science and to encourage exchange between researchers and engineers, Dr Lot Shafai established in 1986 the symposium on “Antenna Technology and Applied Electromagnetics”, ANTEM. Every two years he invites his Canadian colleagues and students to be part of the organization, thus creating tremendous interactions between them and with international researchers. This event is now sponsored by URSI since 2004. In 2005, ANTEM was held for the first time outside Canada in St Malo, France, expanding its exchange and communication mission between continents. This successful experience was renewed in 2012 in Toulouse, France. To share his knowledge and findings he wrote several books and book chapters. One of them, the “Microwave Horns and Feeds” book is still the most valuable source for reflector feed design.

His exemplary career is punctuated with numerous prizes and awards, recognizing the uniqueness of his research outcomes. To name a few, he won in late 70’s the “Premier Award” for industrial design innovation, for his small ground station terminal. In 1984 he received the Professional Engineering Merit Award and in 1985 the <<Thinker>> Award from Canadian Patents and Development Corporation. He received from the University of Manitoba the Research Awards in 1983, 1987, and 1989; the Outreach Award in 1987; and the Sigma Xi Senior Scientist Award in 1989. In 1990, he received the Maxwell Premium Award from the IEE (London), and he was elected a Fellow of the IEEE in 1987, and was elected a Fellow of the Royal Society of Canada in 1998. He was a recipient of the IEEE Third Millennium Medal in 2000, and in 2002 was elected a Fellow of the Canadian Academy of Engineering. In 2003, he received the IEEE Canada “Reginald A. Fessenden Medal” for “Outstanding contributions to telecommunications and satellite communications,” and a Natural Sciences and Engineering Research Council (NSERC) Synergy Award for “Development of advanced satellite and wireless antennas.” He holds a Canada Research Chair in Applied Electromagnetics. In 2009, he was elected a Fellow of the Engineering Institute of Canada, and was the recipient of the IEEE AP-S Chen-To-Tai Distinguished Educator Award. More recently he received in 2011 the Killam Prize in Engineering from the Governor General of Canada for “Outstanding Canadian Carrier Achievement in engineering, and his work in antenna research,” and the 2013 IEEE AP-S John Kraus Antenna Award.

In summary, Dr Lot Shafai has unique and outstanding contributions to telecommunications. His 43-year career witnesses continuous dedication to science, creativity and scientific leadership, and is a remarkable example for the new generation of researchers.

Sincerely Yours,

Dr. Michel Clénet, CNC-URSI Commission B Chair DRDC Ottawa 3701 Carling Avenue Ottawa, ON K1A 0Z4

September 06, 2013 URSI Secretariat, c/o INTEC Ghent University Sint-Pietersnieuwstraat 41 B-9000 Ghent, Belgium Recommendation in support of Professor Lotfollah Shafai for the URS I – Booker Gold Medal Dear Members of the Selection Committee, Professor Lotfallah Shafai is a senior and respected member of our community. He has made seminal contributions mainly in the area of satellite-communication antennas and was an active participant in many Canadian space programs. For example, he conceived and pioneered the design of the first generation pico-terminals for the Canadian Hermes satellite which is currently still in use internationally. The book that he co-authored on “Microwave Horn Antennas and Feeds” (IEE Publications, London) is very highly regarded and is now considered a classic in this field. His outstanding research has won him many awards such as the Reginald Fessenden Award from the Institute of Electrical and Electronic Engineers (IEEE) in Canada, the 2011 Killam Prize Award (one of Canada's most prestigious awards in science and engineering), the IEEE Antennas and Propagation Society’s Chen-To Tai Distinguished Educator Award, and the 2012 John Kraus Award also from the IEEE Antennas and Propagation Society. Professor Shafai is a Fellow of the Royal Society of Canada, a Fellow of the Canadian Academy of Engineers, and a Canada Research Chair in Applied Electromagnetics. In the 1970's Professor Shafai introduced the CAD concept for designing reflector antennas and pioneered computer-based optimization tools for eliminating costly experimental design procedures. In this way, he helped to revolutionize the reflector antenna feed design. One particular application has been in the miniaturization of the Direct Broadcast Satellite (DBS) terminal for the Hermes Satellite, in 1976 mentioned above. Professor Shafai and his team reduced the antenna size to below 2 feet, allowing experiments with tele-medicine

and tele-education in remote communities. This design was quickly adopted internationally for DBS applications and transformed the satellite service industry globally. The next generation of this terminal was implemented by Professor Shafai's team in the late 1990’s at Ka-band, for broadband satellite communication with an even smaller 1 foot antenna. This technology was transferred to NORSAT International in Vancouver, and was commercialized as a mobile video link, still in use. This product has also transformed the satellite service industry, in broadband communications. In summary, Professor Shafai has made significant contributions to the design and analysis of several key feeds for reflector antennas including "Waveguide Feeds", "Dielectric Feeds", "Dipole Feeds", "Microstrip Feeds" and "Resonator type Feeds". Professor Shafai has also made significant contributions to technology innovations for antenna spacecraft applications. In the 1990’s, in collaboration with Spar Aerospace and CRC, he led a team in collaboration with the Universities of Waterloo and Carleton, for the development of successful Ka-band phased arrays for spacecraft applications. He also undertook the development of shared aperture antennas for the next generation of RADARSAT. Prototypes of his antennas were designed and delivered to the Canadian Space Agency (CSA). Moreover, research on V-band phased arrays was initiated using a novel micro-machined membrane technology, and prototypes were designed and delivered to CSA. Professor Shafai has a very impressive record of publications that document all these outstanding contributions over the years. Professor Shafai’s research has always been relevant to practical, high-impact, applications. For example, his early research on satellite terminal antennas enabled Direct Broadcast Satellite programs to become reality. This is also evident by the large number of patents that he holds. As was mentioned previously, for his work and achievements, Professor Shafai has received numerous national and international awards. Some distinguished recent awards include the IEEE Antennas and Propagation Society Chen-To Tai Distinguished Educator Award “For contributions to antenna teaching and research by developing curriculum, numerical techniques, establishing link between industry and university and its impact on students internationally” , the 2011 Canada Council for the Arts, “Killam Prize in Engineering” and the 2012 John Kraus Award from the IEEE Antennas and Propagation Society. Professor Shafai has shown exceptional leadership abilities for the promotion of applied electromagnetics and antennas in Canada and internationally. The most notable example is that he has established the Symposium on Antenna Technology and Applied Electromagnetics (ANTEM) in 1986 which is the premier Canadian symposium on the subject. Likewise, professor Shafai has demonstrated an exceptional ability in the transfer of technology from university to industry. In this regard, he was involved in the formation of a number of start-up companies such as “Broadband Networks Inc”, “Spaceworks” and more recently “Infomagnetics”. At the University of Manitoba Dr. Shafai has assisted establishing the Institute for Technology Development in order to promote university/industry interaction.

In conclusion, Professor Shafai has made major contributions to Radio Science and in particular to antenna technologies for space science and beyond. His research led to several commercialization ventures which verify its significance. The outstanding research achievements of Dr. Shafai and his leadership in Radio Science make him an exceptional candidate for the URSI Booker Gold Medal.

Re: Nomination of Dr. Lotfollah Shafai for the URSI-Booker Gold Medal

Dear Members of the Selection Committee,

I have known Dr. Shafai since 1970 and have worked with him on research projects, many URSI

committees and activities, conferences and theses committees. I consider Dr. Shafai to be one of

the world’s most outstanding applied electromagnetic researchers whose contributions extend

over 45 years.

Dr. Lotfollah Shafai has made several key contributions to the area of telecommunication

research and technology. His early work dealt with both areas of applied electromagnetics

and antennas. He contributed significantly to the early development of numerical

techniques, especially the moment methods. This was instrumental to the development of

the numerical techniques for CAD design of reflector antennas and their feeds. Along with

his students, he developed the first ever numerical modeling technique for corrugated feeds,

which transformed the reflector antenna design from the cut-and-try approach to an exact

science, which was later adopted internationally.

He made significant contributions to the Canadian space program, through his efforts on

the design of spacecraft antennas and investigation of their gain, side lobe, and polarization

characteristics. He also made fundamental contributions to the satellite ground station

antennas, especially the miniaturized terminals for the Canadian Hermes satellite. His

design for the first time reduced the antenna size below 60 em, which allowed

economical use of satellites for direct-broadcastsystems, especially for launching tele-

medicine and tele-education in remote Canadian communities. His efforts in this area

definitely constitute a major contribution to Canadian communication technology, and

transformed the satellite communication industry, from the domain of big corporations to

an economic tool for all Canadians, with significant impact in the lives of Canadian in small

communities, and economic wellbeing of small telecommunication companies.

He has also made special efforts to transfer his research results into industrial products by

helping small industries to become competitive, and assisting his own students in

incorporating successful industries from their own university research. They contributed

significantly to the advancement of satellite and wireless communication industry in Canada,

and were instrumental in developing successful products and employment to young

engineers. For example, his students developed and commercialized the first terrestrial

communication link at 30 GHz in Canada, from their own university-based research,

which was subsequently adopted internationally.

His recent contributions, through the Canada research chair program, have continued on

similar disciplines, the main ones being on hardware miniaturization and arctic research.

The by-product of his research on hardware miniaturization has been three different

innovations in communication hardware development, which are:

• The development of new low loss laminated conductors,

• The development of low loss communication hardware and antennas, using high

permittivity ceramics, and

• The development of virtual array concept for hardware minimization.

The development of low loss laminated conductors is a significant breakthrough in

engineering and helps the advancement of the current conductor based hardware designs

into the millimeter wave and THz bands. His laminated conductor concept makes the

resistive loss of conventional conductors nearly independent of frequency, and in terms of

classical electromagnetic phenomenon, the efficiency of the antennas, filters, amplifiers,

and transmission lines improves dramatically. His contribution in this area will have

profound effects on the advancement of telecommunication industry by facilitating the use

of existing designs in upper frequencies.

His contribution to the development of low loss components, using high permittivity

ceramics, is complementary to his work on laminated conductors, and will launch a new

design concept for RF component developments, where the conductor use become

impractical. It will also facilitate the advancement of communication technology into

millimeter wave and THz bands.

His virtual array concept developed initially for high gain reflector antennas, allows the

transformation of the conventional reflector antenna into an array, providing all benefits of

the arrays to the reflector antenna industry. It also, helps in porting the Multiple-Input

Multiple-Output, MIMO, technology into the reflector antenna applications. The influence of

this double innovation in the reflector antenna technology is very profound, as it transforms it

from only a simple high gain antenna into a multi- function device that also includes the

signal processing function.

His Arctic research is concentrated on the modeling of Arctic sea ice, and investigation of

the climatic change. This is a significant effort, as Arctic research is physically demanding,

scientifically challenging, and very costly. It is, however, fundamental to understanding of

the natural processes in the Arctic region, and the establishment of sustainable

communication system in the Arctic, and the expected year-long transportation system. To

understand the significance of this research one must note that, currently Canada has no

capability for wireless or satellite communication in the Arctic region, which falls above

the direct line of sight of geostationary satellites. Establishment of economic

communication systems in the Arctic is dependent on understanding the nature of the

Arctic ice cover, and our understanding of the satellite based observations. The research of

the nominee will help in providing proper real time calibrating data for satellite

observations, which currently is non-existent.

In summary, Dr. Shafai has made significant contributions to the advancement of the

communication technology in Canada, and the world. He is a deserving candidate for the

URSl Booker gold medal.
