More Information
Summary:Provided is a wireless power transmission method and apparatus for improving spectrum efficiency and space efficiency based on impedance matching and relay resonance, the method including detecting an input impedance at a resonant frequency, matching a transmitting port impedance to a real number value of the detected input impedance, and transmitting power to a receiving resonator smaller than a transmitting resonator using the relay resonator.
