Resonant Wireless Power Transfer (RWPT), introduced by MIT researchers in 2008, is a Wireless Power Transfer (WPT) that has compensation capacitors in both the transmitter and receiver and operating at their resonant frequency. The compensating capacitors make a big difference when compared to a WPT.
