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 minimize loss in at least one resonator.
