1. A resonant power transmission system for wirelessly delivering electric power to a target device, the resonant power transmission system comprising:

  • a transmitter resonant phased array comprising;

    a power source operable to source alternating current power at a target frequency;

    a plurality of transmitting elements, each operable to produce a non-radiated magnetic field, the plurality of transmitting elements operable to produce a composite non-radiated magnetic field;

    a plurality of transmitter tuned circuit elements operable to couple the alternating current power to the plurality of transmitting elements; and

    control circuitry operable to control the plurality of transmitter tuned circuit elements to direct the composite non-radiated magnetic field toward the target device; and
