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.

Sorting out quantum chaos in the microwave lab
4/29/95
Depending on the table's shape, the motion of a billiard ball can be either predictable or chaotic. The same physical laws determine the outcome in either case, but in the chaotic situation the result is sensitively dependent on initial conditions.
