Standing Wave Induced Field Focusing Transceiver for Wireless Capacitive Power Transfer

Single Contact Wireless Capacitive Power Transfer (CPT) is an emerging technology that offers many useful advantages including high transfer efficiency, enhanced misalignment tolerance, and low fabrication costs. Most contemporary CPT methods rely only on a transmitter/receiver geometry in an attempt to mitigate the stray fields. To reduce the leakage electric flux within a CPT environment, a new technique is presented in this paper that relies on standing wave field patterns to intensify the coupling between the transmitter/receiver, while simultaneously suppressing the leakage flux in the adjacent space around the system.
