Abstract
A method and system for wireless power transfer are provided. The method includes adapting first and second variable form factor transmitters into at least first and second sets of cross-coupled segments, respectively, disposed about a pre-determined wireless power transfer area and spatially offset from one another by a preselected spatial offset that minimizes inductive coupling between the first and second sets of cross-coupled segments, transmitting, from first and second radio frequency (RF) power sources electrically coupled to the first and second sets of cross-coupled segments, respectively, RF power across the pre-determined wireless power transfer area via near electromagnetic fields of the variable form factor transmitters such that a magnetic field associated with the near electromagnetic fields rotates in a pattern having a preselected shape.
