Disclosed herein is a wireless power delivery system including: a wireless power generation unit (GU) including: a GU antenna array; and a GU wireless communication circuit; and one or more recovery units (RUs), wherein each RU includes: an RU antenna array; and an RU wireless communication circuit. The GU antenna array is configured to use volumetric refocusing to scan the area for the one or more RUs by sweeping a wireless scan signal to be captured by the RU antenna array. The RU antenna array receives the wireless scan signal, the RU wireless communication unit is configured to transmit a wireless signal back to the GU wireless communication unit. The GU is configured to record the focal coordinates of each RU based upon the signal received by the GU from each RU. The GU is configured to emit a wireless power signal to the recorded focal coordinates of each RU.
