Abstract :
Resonant Wireless Power Transfer (WPT) can be realized by using coils coupled via their magnetic fields; such systems can exchange energy in the mid-range. Information can also be exchanged via Near-Field Magnetic Communications (NFMC), which is currently receiving considerable attention for several possible applications. We present a structure that can be used for realizing both WPT and NFMC; this structure shows separate frequency channels for the simultaneous transmission of power and data. A test system with one band for power exchange and two separate bands for data transmission is designed, simulated, and measured to show the effectiveness of the proposed structure.
