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