  • Apparatus and method for providing a selectively absorbing structure
    Patent number: 10976636
    Abstract: 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.
    Type: Grant
    Filed: February 2, 2017
    Date of Patent: April 13, 2021
    Assignee: Duke University
    Inventors: David R. Smith, Antoine Moreau, Cristian Ciraci, Jack J. Mock
