1. Metamaterials, some drawn some not. Boris Kuhlmey 10/8/12

2. Natural atom “Meta”-atom Metamaterials  e  Optical properties from structure, not composition

3. 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
