1. An enhanced wireless power transfer (WEPT) transmitter comprising:
a power transmission coil having an axis;
a power source operable to generate a time varying current IT in the power transmission coil that generates a time varying magnetic B field; and
at least one eddy current conductor shaped and positioned to generate eddy currents responsive to the time varying current in the power transmission coil that produce an equivalent of a virtual mirror image of IT which enhances the time varying magnetic B field generated by the time varying current;
wherein the at least one eddy current conductor extends alongside the axis and is absent slits or holes that may operate to distort the virtual mirror image of IT.
