1. A method for 3-dimensional pocket-forming in wireless power transmission, comprising the steps of:

  • capturing a first signal from a receiver with a first subset of antennas from an antenna array on a transmitter;

    switching to a different subset of antennas on the transmitter;

    capturing a second signal from the receiver with a second subset of antennas from the antenna array on the transmitter; and

    processing the first and second signals by a microprocessor on the transmitter in order to adjust the antenna array on the transmitter to form pockets of energy directed to the receiver to charge or power an electronic device.
