	<span style=\"font-size:12pt;\"><span> </span></span><span style=\"color:black;\">We propose a novel resonator that can reduce magnetic field leakage using a ferrite plate. The proposed resonator consists of a rectangular loop, a ferrite plate, and an L-matching network. The ferrite plate is used as an H-field reflector to direct more H-field to each resonator, and the L-matching network is employed to match the 50 ¦¸ of the feed cable at 13.56 MHz. Two identical resonators with dimensions of 30 cm ¡Á 15 cm are separated by 50 cm, and the resulting transmission efficiency is about <span style=\"font-size:6.5pt;font-family:;\" \"=\"\"><span style=\"line-height:13px;white-space:normal;\"><span style=\"font-size:6.5pt;font-family:;\" \"=\"\">?</span></span></span>12.3 dB at 13.56 MHz. This is about 4.2 dB higher than the resonators without the ferrite plate.</span><span></span>
