Patent ID: 8643530

Claim:
An apparatus for reducing a backscatter echo of an electromagnetic wave incident on a target object, comprising: an electrically conducting target object, the electrically conducting target object reflecting the incident electromagnetic wave to create reflected waves in a plurality of scattering directions; and an electrically conducting polyhedral conducting mesh (PCM) surrounding the target object, the PCM substantially conforming to a shape of the target object and comprising a surface grid of polyhedrons each having a plurality of edges and an associated plurality of vertices, each of the edges having a length and a width, a length of the edges being much less than one half of a wavelength of an anti-backscatter frequency of the incident electromagnetic wave; wherein the PCM is configured to produce an induced electric field between the PCM and the target object when the target object is subjected to the incident electromagnetic wave, the induced electric field being configured to create interference between the incident electromagnetic wave and the reflected waves that reduces or cancels the reflected waves in a backscatter direction toward a source of the incident electromagnetic wave, thereby reducing the backscatter echo of the electromagnetic wave from the target object.
