Abstract
An arrangement, system and method are described which enhance efficiency, reduce the stray field of wireless power transfer, and make use of special coil geometries for transmitter and receiver. The coil geometry is an approximation of a multipole current. Such currents have a faster decaying electromagnetic field compared to traditional coils. This allows higher power densities to be transferred.
