Abstract: A planar spiral induction coil includes a strip-shaped coil having at least one turn. The at least one turn has a width that changes as a distance from a beginning of the strip-shaped coil increases in a length direction of the strip-shaped coil. Each turn of the at least one turn has a respective width that causes an equal current to flow through each turn of the at least one turn.

Abstract: A wireless charging system and method are provided, that are capable of simultaneously charging multiple mobile devices, providing high power transfer efficiency for multiple mobile devices located at any position and orientation, and minimizing electromagnetic radiation from a transmitting (TX) coil and a receiving (RX) coil. The method and structure reduce electromagnetic interference (EMI) radiation by shunting in-phase currents flowing in a wireless power transmitting unit (TX unit) and a wireless power receiving unit (RX unit) of a wireless charging system.

Abstract: An apparatus configured to transceive wireless power, includes a magnetostrictive resonator configured to be excited by a magnetic field, and a soft magnetic material disposed in a vicinity of the magnetostrictive resonator. The apparatus further includes a transducing coil disposed in a vicinity of the magnetostrictive resonator or the soft magnetic material, and configured to convert mechanical energy generated by the excitation of the magnetostrictive resonator to electric energy.
