Apparatus and method for transceiving wireless power

An apparatus configured to transceive wireless power, the apparatus comprising:

• magnetostrictive resonators configured to be excited by a magnetic field;
• and
• a transducing coil disposed in a vicinity of the magnetostrictive resonators, and configured to convert mechanical energy generated by the excitation of the magnetostrictive resonators to electric energy.

A matching method of a wireless power transmitting apparatus comprising a magnetostrictive resonator and a transducing coil, the method comprising:

• measuring an amount of power transmitted by the wireless power transmitting apparatus to a wireless power receiving apparatus;
• and
• adjusting a number of turns of the transducing coil, and/or positions of the transducing coil and the magnetostrictive resonator, until the measured amount of power is maximized.
