"For elegant experiments providing seminal insights on left-handed metamaterials, quantum chaos, vortex and quasiparticle electrodynamics in superconductors, and collective excitations in low-dimensional materials." - APS Physics, 19 November 2007

First Demonstration of Focusing by Plano-Concave Lens
4/7/05
We demonstrate focusing of a plane microwave by a planoconcave lens fabricated from a photonic crystal having a negative refractive index and left-handed electromagnetic properties.

First Demonstration of Imaging by Flat Lens
11/27/03
The positive refractive index of conventional optical lenses means that they need curved surfaces to form an image, whereas a negative index of refraction allows a flat slab of a material to behave as a lens and focus electromagnetic waves to produce a real image.
