Abstract:
In embodiments of the present invention improved capabilities are described for a method and system comprising a first resonator coupled to an energy source generating a field having magnetic material, and a second resonator located a variable distance from the source resonator having magnetic material and not connected by any wire or shared magnetic material to the first resonator, where the source resonator and the second resonator are coupled to provide near-field wireless energy transfer among the source resonator and the second resonator, and where the field of at least one of the source resonator and the second resonator is shaped using magnetic materials to increase the coupling factor among the resonators.
