  • Metamaterial surfaces
    Patent number: 9105979
    Abstract: An apparatus to modify an incident free space electromagnetic wave includes a block of an artificially structured material having an adjustable spatial distribution of electromagnetic parameters (e.g., ?, ?, ?, ?, and n). A controller applies control signals to dynamically adjust the spatial distribution of electromagnetic parameters in the material to introduce a time-varying path delay d(t) in the modified electromagnetic wave relative to the incident electromagnetic wave.
    Type: Grant
    Filed: October 22, 2010
    Date of Patent: August 11, 2015
    Inventors: Jeffrey A. Bowers, Roderick A. Hyde, Jordin T. Kare, Nathan Kundtz, Bruce Marshall McWilliams, John Brian Pendry, David Schurig, David R. Smith, Anthony F. Starr, Clarence T. Tegreene, Lowell L. Wood, Jr.
