1. A wireless power transfer system including:
a. a power transmitter including:
i. a magnetically permeable transmitter core having a base portion and an axial core portion extending away therefrom along a magnetic field propagation axis, wherein the base portion extends further away from the magnetic field propagation axis than the axial core portion;ii. transmitter windings provided about the axial core portion; andiii. an AC power supply driving the windings to produce an oscillating magnetic field; and b. a power receiver including:
i. a magnetically permeable receiver core having a base portion and an axial core portion extending away therefrom along a magnetic field reception axis, wherein the base portion extends further away from the magnetic field reception axis than the axial core portion;ii. receiver windings provided about the axial core portion; andiii. a power receiver circuit receiving an AC current from the windings induced by the oscillating magnetic field.
