1. A system for wireless power transmission, the system comprising:

  • a transmitter comprising;

    a plurality of antennas configured to transmit power waves that constructively interfere with one another to form a pocket of energy to power a targeted electronic device coupled with a receiver; and

    a processor configured to (i) dynamically adjust respective positions of each of the plurality of antennas and (ii) determine a location of the receiver,wherein;

    the plurality of antennas is arranged in a three-dimensional non-planar shape,the processor is also configured to;

    dynamically adjust at least a respective position of a first antenna of the plurality of antennas so that the three-dimensional non-planar shape is dynamically adjusted based on the location of the receiver, andselect two or more antennas from the plurality of antennas to actively transmit the power waves, andfurther wherein;

    while the plurality of antennas has the dynamically adjusted shape, the two or more antennas are configured to transmit the power waves with a radiation pattern that has a main lobe axis directed towards the location of the receiver, anda first amount of energy associated with the pocket of energy is greater than a second amount of energy present outside a periphery of the pocket of energy.
