1. Scope and objective of the course:

Electromagnetics is a subject which deals with electric field, magnetic field and the waves constitutedby the fields. The revolution in modern electromagnetics started when some experimental laws weregeneralized and unified into the so called Maxwell's equations which later formed the basis of explaining almost all phenomena found in Electrical and Communication Engineering. The

electromagnetic force play pivotal role in electrical machines, communication antennas, microwaveovens, radio frequency particle accelerators, PCBs operating at GHz clocks and even in impartingcertain biological effects. This course is divided into two parts- theory and engineering. The theorypart will cover concepts like propagation, storage and dissipation of EM waves. The engineering partwill use the theoretical understanding to analyze structures such as transmission lines, waveguidesand cavity resonators. Emphasis will be placed on the most used range of the EM spectrum - themicrowaves.
