  • Electromagnetic cloaking method
    Patent number: 10302400
    Abstract: A method of constructing a concealing volume comprises constructing a plurality of concealing volume elements around a concealable volume. Each concealing volume element has a material parameter arranged to direct a propagating wave around the concealable volume. The material parameter can be refractive index, electrical permittivity, and magnetic permittivity. The concealing volume can be a metamaterial. The concealing volume diverts incoming propagating waves such that outgoing propagating waves appear to be unperturbed to an observer.
    Type: Grant
    Filed: June 12, 2017
    Date of Patent: May 28, 2019
    Assignees: Duke University, Imperial Innovations Limited
    Inventors: John Pendry, David Smith, David Schurig

  • NARROW BEAM ANTENNAE
    Publication number: 20050099348
    Abstract: A method for making an antenna and the antenna itself are described. The antenna comprises a first region having a first refractive index and a second region having a negative refractive index, the second region substantially surrounding the first region, such that radiation outside the second region is reproduced in the first region.
