Constant capacitive wireless power transfer at variable coupling [PDF]
2018 IEEE MTT-S International Wireless Symposium (IWS), 2018 Capacitive wireless power transfer uses the varying electric field for wireless power transfer from a transmitter plate to a receiver plate. The amount of power transferred to the load and the system efficiency are dependent of the coupling between transmitter and receiver.
