1. A power delivery system for wirelessly delivering electric power to a target device and for delivering a communication signal to the target device, the power delivery system comprising:

  • a power transmitting unit comprising;

    a power source operable to source alternating current power;

    a sending resonant coupling component operable to couple the alternating current power to a coil for wireless power transmission by a non-radiated magnetic field at a target resonant frequency;

    the power transmitting unit capable of dynamically tuning the wireless power transmission to the target resonant frequency wherein the target resonant frequency is specified dynamically; and

    a communication module coupled to the power transmitting unit and operable to couple the communication signal to the non-radiated magnetic field.
