1. A method for wireless transfer of power from a wireless charger to an implantable component having an implantable coil, the method comprising:

  • delivering a first alternating current signal to a first coil antenna of the wireless charger so as to produce a first magnetic field;

    delivering a second alternating current signal to a second coil antenna of the wireless charger so as to produce a second magnetic field, wherein the second alternating current signal causes at least one of the phase or amplitude of the second magnetic field to vary with respect to the phase or amplitude of the first magnetic field; and

    receiving, at the implantable coil, a combined magnetic field comprised of the first and second magnetic fields, wherein the combined magnetic field generates an alternating current signal at the implantable coil.
