Electromagnetic Field Exposure Feature of a High Resonant Wireless Power Transfer System in Each Mode

This paper presents the dosimetry of a high resonant wireless power transfer (WPT) system under the conditions of a single resonant mode and two resonant modes: even and odd modes, which occur when the two transmitting and receiving resonators are very close to each other. The specific absorption rates (SARs) are calculated with simplified head-size and body-size human models placed at various distances from the WPT system and in each mode. Results show that the electric and magnetic fields of the odd mode distributes stronger than those of the odd mode in the area near to the WPT system, while the opposite results are found in the far area.
