Source radio frequency energy (RF) is coupled wirelessly, with no direct physical contact, between two compound loop (CPL) antennas across a variety of barriers such as plastic, human tissues, glass, and air. The compound coupling interface is highly efficient in transferring the RF energy from a source including one CPL antenna to a destination including a second CPL antenna. A re-radiating structure including a further CPL antenna or a different type of antenna may be connected on the destination side to completely physically isolate the source side from the destination side. When the destination coupling antenna is removed, the source coupling antenna may operate as an efficient radiator at the desired operating frequencies. Likewise, the destination coupling antenna may operate as an efficient radiator in the absence of the source coupling antenna.

A gradient index lens for microwave radiation. The lens includes a plurality of electric field coupled resonators wherein each resonator has a resonant frequency. The resonators are arranged in a planar array having spaced apart side edges and spaced apart top and bottom edges. The resonant frequency of the resonators varies between at least two of the spaced edges of the array in accordance with the desired properties of the lens.
