1. A method of wireless power transmission system, the method comprising:

  • calculating, by a transmitter, a specific absorption rate (SAR) value at each 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;

    determining, by the transmitter, a selected portion within the transmission field where the calculated SAR value fails a pre-defined SAR value threshold; and

    transmitting, by the transmitter, the one or more power waves to converge destructively at or proximate to the selected portion within the transmission field.
