1. A system, comprising:

  • a source resonator optionally coupled to an energy source; and

    a second resonator located a distance from the source resonator,wherein the source resonator and the second resonator are coupled to provide near-field wireless energy transfer among the source resonator and the second resonator,wherein the field of at least one of the source resonator and the second resonator is shaped using conducting surfaces to increase the coupling factor among the resonators.
