Metamaterials found to work for visible light (PhysOrg.com)

Ames Laboratory researchers have found the first metamaterial known to work for visible light, announcing the discovery in the Jan. 5 issue of Science.

For the first time ever, researchers at the U.S. Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light. Ames Laboratory senior physicist Costas Soukoulis, working with colleagues in Karlsruhe, Germany, designed a silver-based, mesh-like material that marks the latest advance in the rapidly evolving field of metamaterials, materials that could lead to a wide range of new applications as varied as ultrahigh-resolution imaging systems and cloaking devices.
