Anisotropic Metamaterials for Electromagnetic Compatibility (Continuation)

Anisotropic Metamaterials for Electromagnetic Compatibility (Continuation)
Inventors: Raymond Rumpf, Cesar Garcia
Patent No. 9,893,432

This patent incorporates metamaterials to provide strong anisotropy and a mechanism for spatial variance. Reshaping near-fields around multiple components placed in close proximity can improve electromagnetic compatibility between components. SVAMs have been shown to be able to reshape the near-field around electrical devices by adjusting the orientation of the anisotropy as a function of position. The near-field takes on the same shape as the spatial variance. This sculpting behavior is the mechanism by which devices in close proximity can be electromagnetically decoupled to improve their compatibility.

An electromagnetic device includes: a first layer having a first material with a first dielectric constant, the first layer having a plurality of channels or holes filled with a second material with a second dielectric constant that is different from the first dielectric constant; and, a second layer having a plurality of antennas disposed on the first layer. Adjacent ones of the plurality of channels of the first layer have an average spacing therebetween of less than one quarter of an operating wavelength of at least one of the plurality of antennas.
