Optical properties from structure, not composition

Metamaterials - applications

– Transform optics:

• Cloaking and invisibility

• Deception optics

• GRIN devices/Perfect lenses/flat lenses also for antennas

– Filtering eg ultra-thin filters

– Subwavelength confinement

– Super resolution (super/hyper lenses)

– DOS manipulation and emitter/antenna design

– Slow light, funky phase matching

– Sensing
