Abstract
A network for power transmission to a receiver which converts the power into current includes a first node for transmitting power with circularly polarized waves in a first area. The network includes a second node for transmitting power with circularly polarized waves in a second area. Alternatively, elliptically polarized waves or dual polarized waves are used or different frequencies are used or different polarizations are used or different polarization vectors are used. Also disclosed is a method for power transmission to a receiver which converts the power into current.
