1. A system for wireless power transmission, the system comprising:
- a plurality of transmit tiles configured to operate as one functional unit, each of the transmit tiles comprising;
one or more antennas,a radio frequency integrated circuit (RFIC) coupled to the one or more antennas and configured to engage the one or more antennas such that the antennas of the plurality of transmit tiles emit a plurality of wireless power waves forming constructive and destructive interference patterns defining a controlled pocket of energy exclusively at a location of a wireless power receiver, anda controller coupled to the RFIC and configured to determine efficient trajectories along which to transmit the plurality of wireless power waves to form the pocket of energy at the location of the wireless power receiver, wherein the efficient trajectories reduce transmission losses by avoiding obstacles located between the system and the location of the wireless power receiver.

19. A method of using transmit tiles to wirelessly deliver power to a wireless power receiver, the method comprising:
at a controller that is coupled with a plurality of transmit tiles configured to operate as one functional unit, each respective transmit tile comprising one or more antennas and a radio frequency integrated circuit (RFIC) coupled to the one or more antennas; instructing the RFIC to engage the one or more antennas such that the antennas of the plurality of transmit tiles emit a plurality of wireless power waves forming constructive and destructive interference patterns defining a controlled pocket of energy exclusively at a location of the wireless power receiver, and determining efficient trajectories along which to transmit the plurality of wireless power waves to form the pocket of energy at the location of the wireless power receiver, wherein the efficient trajectories reduce transmission losses by avoiding obstacles located between the plurality of transmit tiles and the location of the wireless power receiver.

20. A non-transitory computer-readable storage medium comprising executable instructions that, when executed by a controller that is coupled with a plurality of transmit tiles configured to operate as one functional unit, each of the transmit tiles comprising one or more antennas and a radio frequency integrated circuit (RFIC) coupled to the one or more antennas, cause the controller to:
-
instruct the RFIC to engage the one or more antennas such that the antennas of the plurality of transmit tiles emit a plurality of wireless power waves forming constructive and destructive interference patterns defining a controlled pocket of energy exclusively at a location of a wireless power receiver, and determine efficient trajectories along which to transmit the plurality of wireless power waves to form the pocket of energy at the location of the wireless power receiver, wherein the efficient trajectories reduce transmission losses by avoiding obstacles located between the plurality of transmit tiles and the location of the wireless power receiver.
