Abstract
In embodiments of the present invention improved capabilities are described for a method and system comprising a source resonator optionally coupled to an energy source and a second resonator located a distance from the source resonator, where the source resonator has Q>100 and the second resonator has Q>100, 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 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.
