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.

Optimal Coupling for Capacitive Wireless Power Transfer with One Repeater
2022 52nd European Microwave Conference (EuMC), 2022 Abstract: In order to extend the range of capacitive wireless power transfer, an electric field repeater between transmitter and receiver can be applied. In this work, a network formalism is adopted to analytically describe and maximize the system efficiency of a repeater setup. The resonator components, resistive losses, load and supply impedances are
