1. A load impedance decision device comprising:

  • a measurement unit configured to measure at least one of a distance and an angle between a source resonator and a target resonator; and

    a decision unit configured to determine the load impedance based on at least one of the measured distance and the measured angle;

    wherein the source resonator is configured to transmit resonant power to the target resonator based on the load impedance that is determined based on at least one of the measured distance and the measured angle.
