Abstract

Researchers present a novel and broadly applicable way to increase magnetic coupling between two distant elements, by using the properties of extreme anisotropic magnetic metamaterials. They analytically demonstrate how the magnetic coupling between emitting and receiving coils in a general system can be enhanced by surrounding them with magnetic metamaterials, exactly as if the distance between them has been reduced. The validity of the theoretical results are confirmed by experimentally demonstrating that using magnetic metamaterials results in a boost on the efficiency in the wireless transmission of power between circuits, since this efficiency directly depends on the magnetic coupling between emitter and receiver.
