Abstract (en)
[origin: WO2017117452A1] Systems and methods disclosed herein related to wireless power transmission system. In one example method: a transmitter measures a plurality of specific absorption rate (SAR) values, each respective SAR value corresponding to a respective spatial location within a transmission field of the transmitter with respect to one or more power waves radiated from one or more antennas of the transmitter. The transmitter also determines a selected spatial location within the transmission field where a first measured SAR value of the plurality of SAR values does not satisfy a pre-defined SAR value threshold. The transmitter further transmits the one or more power waves to converge destructively at or proximate to the selected spatial location within the transmission field.
