Abstract(in English) Wireless Power Transfer (WPT) system and Near Filed Communication (NFC) is being installed in smart phone. However, their receiving coils in a smartphone are installed near battery or some metallic objects, which causes the problem of decreasing transmission efficiency. To solve this problem, magnetic sheet have been used between Rx-coil and battery . This research studies the optimization both of effective power transmission of WPT and effective RF communication of NFC with one sheet to minimize the size of magnetic sheet.
