APPARATUS AND METHOD FOR PROVIDING A SELECTIVELY ABSORBING STRUCTURE

摘要

An apparatus is described that selectively absorbs electromagnetic radiation. The apparatus includes a conducting surface, a dielectric layer formed on the conducting surface, and a plurality of conducting particles distributed on the dielectric layer. The dielectric layer can be formed from a material and a thickness selected to yield a specific absorption spectrum. Alternatively, the thickness or dielectric value of the material can change in response to an external stimulus, thereby changing the absorption spectrum.
