Abstract
A method for wireless power transfer. The method includes adapting a variable form factor transmitter into at least a plurality of cross-coupled segments disposed about a pre-determined wireless power transfer area, wherein the pre-determined wireless power transfer area comprises a dimension exceeding a wavelength corresponding to a characteristic frequency of the variable form factor transmitter, transmitting, from a radio frequency (RF) power source and based at least in part on the characteristic frequency, RF power across the pre-determined wireless power transfer area via a near electromagnetic field of the variable form factor transmitter, and reducing, based on opposing directions of magnetic fields induced by adjacent cross-coupled segments of the plurality of cross-coupled segments, a radiation loss of the wireless power transfer due to a far electromagnetic field of the variable form factor transmitter.
