1. A 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,wherein the first resonator and the second resonator are coupled to provide near-field wireless energy transfer among the first resonator and the second resonator;

    wherein the field of at least one of the first resonator and the second resonator is shaped to increase the coupling factor among the resonators.
