Abstract
A method for wireless power transfer. The method includes adapting a variable form factor transmitter into an adapted form factor based on a pre-determined wireless power transfer area, wherein the variable form factor transmitter in the adapted form factor comprises a characteristic frequency, maintaining the characteristic frequency to be substantially independent of the adapted form factor, and 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.
