DESIGN OF A WIRELESS CAPACITIVE POWER TRANSFER SYSTEM [PDF]
International Journal on Smart Sensing and Intelligent Systems, 2017 Abstract This paper presents the design of a capacitive power transfer (CPT) system by using the Class-E amplifier approach. The Class-E amplifier approach is chosen to be adopted since it produces high efficiency as close as to 100%, theoretically.

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.

Optimum Receiver-Side Tuning Capacitance for Capacitive Wireless Power Transfer [PDF]
Electronics, 2019 This paper reveals the optimum capacitance value of a receiver-side inductor-capacitor (LC) network to achieve the highest efficiency in a capacitive power-transfer system. These findings break the usual convention of a capacitance value having to be chosen such that complete LC resonance happens at the operating frequency. Rather, our findings in this
