'Metasurfaces' to usher in new optical technologies
Date:3/14/2013

te materials with an index of refraction that's negative or between one and zero promises a range of potential breakthroughs in a new field called transformation optics.

Development of new technologies using metamaterials has been hindered by two major limitations: too much light is "lost," or absorbed by metals such as silver and gold contained in the metamaterials, and the materials need to be more precisely tuned so that they possess the proper index of refraction.

Ultrathin metasurfaces made of novel low-loss plasmonic material components is a promising way to address this challenge. Researchers are working to replace silver and gold in materials that are created either by making semiconductors more metallic by adding metal impurities to them; or adding non-metallic elements to metals, in effect making them less metallic. Examples of these materials include transparent conducting oxides and titanium nitride, Boltasseva said.
