Abstract
A method for wireless energy transfer includes forming a plurality of energy beams. Each energy beam includes one or more electromagnetic (EM) waves having a same fundamental frequency as another EM wave of another one of the energy beams. A device response of an energizable device to the plurality of energy beams incident thereon is tracked. The one or more EM waves for each of the plurality of energy beams is directed to power the energizable device. A respective phase of the one or more EM waves for at least one of the energy beams is aligned to another phase of another EM wave of another one of the energy beams. A received power level received by the energizable device is maximized according to the device response by optimizing for at least one of the energy beams, the directing, and the aligning of the phase, of the one or more EM waves.
