Frequency-division technique for simultaneous wireless power transfer to two receivers

In this paper, we propose a frequency division technique for transferring wireless powers simultaneously to two receivers. The network is composed of one transmitter and two receivers, with three matching networks to match the two loading coils to the source at two different frequencies. The application scenario and the corresponding circuit model are presented. An illustrative example is finally analyzed to validate the proposed technique. The proposed frequency division approach can be potentially extended to multiple receivers.
