Analytical Study on the Performance of a Hybrid Inductive-Capacitive Wireless Power Transfer System
2025 IEEE Wireless Power Technology Conference and Expo (WPTCE)Inductive wireless power charging applies the magnetic field to transfer power from one coil to another. In contrast, capacitive wireless power transfer uses the electric field as medium.

The Behaviour of a Capacitive Wireless Power Transfer System with an Arbitrary Number of Repeaters
Annual Conference of the IEEE Industrial Electronics SocietyCapacitive wireless power transfer systems often suffer from limited range due to the rapid decay of the electric field with distance. Introducing electric field repeaters can help extend the range, but their effect on impedance matching and overall ...
