1. A system for wireless energy transfer comprising:

  • a tracking module configured to determine a device response of an energizable device to an energy beam incident thereon, the energy beam comprising a plurality of electromagnetic (EM) waves;

    a first beamforming module configured to direct a first one of the plurality of EM waves to power the energizable device;

    a second beamforming module physically separate from the first beamforming module and configured to direct a second one of the plurality of EM waves to power the energizable device, wherein the first EM wave has a first fundamental frequency equal to a second fundamental frequency of the second EM wave;

    a phase alignment module configured to align for an in-phase arrival at the device, a first phase of the first EM wave with a second phase of the second EM wave; and

    a processing module configured to communicate with at least one of the tracking module, the first beamforming module, the second beamforming module and the phase alignment module to maximize a received power level received by the energizable device according to the device response, the received power level proportional to a transmitted power level of the energy beam formed from a first energy beam including the first EM wave and a second energy beam including the second EM wave, wherein a first energy bubble is formed at the energizable device and a second energy bubble is formed at a second energizable device.
