1. A system, comprising:

  • a source resonator adapted to be 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 andwherein a loss inducing object is positioned to minimize loss in at least one resonator.
