US Patent 9190738 Projected artificial magnetic mirror

A projected artificial magnetic mirror (PAMM) includes conductive coils, a metal backing, and a dielectric material. The conductive coils are arranged in an array on a first layer of a substrate and the metal backing is on a second layer of the substrate. The dielectric material is between the first and second layers of the substrate. The conductive coils are electrically coupled to the metal backing to form an inductive-capacitive network that, for a a selected frequency band, substantially reduces surface waves along a PAMM surface, the PAMM surface residing within the substrate or above the substrate. The PAMM surface may be substantially adjacent or coexistent with the first layer.
