Wire pairs may enable materials for use at optical wavelengths.

Anne L. Fischer

Negative-refractive-index materials bend electromagnetic waves in a direction opposite that of ordinary media with positive refractive indexes, enabling a variety of novel applications, including flat lenses. A group of scientists at Iowa State University and at Ames Laboratory, both in Ames, and at the University of Crete in Iraklion, Greece, has demonstrated a simple way of developing negative-index materials using periodic arrays of pairs of H-shaped metallic wires. When an electromagnetic wave encounters a slab of material with a negative refractive index, it bends in a direction...Read full article
