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 and the second resonator are coupled to provide near-field wireless energy transfer among the source resonator and the second resonator, and where a loss inducing object is positioned to increase the coupling the coupling factor among the resonators.
