Patent number: 10976636Abstract: 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: GrantFiled: February 2, 2017Date of Patent: April 13, 2021Assignee: Duke UniversityInventors: David R. Smith, Antoine Moreau, Cristian Ciraci, Jack J. Mock

Patent number: 8830556Abstract: One exemplary metamaterial is formed from a plurality of individual unit cells, at least a portion of which have a different permeability than others. The plurality of individual unit cells are arranged to provide a metamaterial having a gradient index along at least one axis. Such metamaterials can be used to form lenses, for example.Type: GrantFiled: September 9, 2011Date of Patent: September 9, 2014Assignee: The Regents of the University of CaliforniaInventors: David R.

Publication number: 20140209683Abstract: A method and apparatus for identifying an object having a pattern of plasmon resonant particles (PREs) distributed in or on the object are disclosed. In the method, a field containing the pattern is illuminated, and one or more spectral emission characteristics of the light-scattering particles in the field are detected. From this data, an image of positions and spectral characteristic values in the field is constructed, allowing PREs with a selected spectral signature to be discriminated from other light-scattering entities, to provide information about the field. The image may be compared to a database of reference images to identify or validate the object.Type: ApplicationFiled: March 26, 2014Publication date: July 31, 2014Applicant: The Regents of the University of CaliforniaInventors: Sheldon Schultz, David A. Schultz, David R. Smith, Jack J. Mock, Thomas J. Silva
