First Demonstration of Focusing by Plano-Concave Lens

P. Vodo, P. V. Parimi, W. T. Lu and S. Sridhar Applied Physics Letters, V.86, P.201108 (2005) 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. An inverse experiment, in which a plane wave is produced from a source […]

First Demonstration of Imaging by Flat Lens published in Nature

First Demonstration of Imaging by Flat Lens 11/27/03 P. Parimi, W. T. Lu, P. Vodo and S. Sridhar Nature, V. 426, P. 404 (2003) 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 […]

Sorting out quantum chaos in the microwave lab

Ivars Peterson Science News, P. 264 (1995) A smooth stroke ending in a sharp tap with a billiard cue sends a ball scooting across the table’s green felt surface. The ball bounces off one cushion, then another before smacking squarely into a second ball. On a rectangular table, an expert player can return the first […]
