Gain Expressions for Capacitive Wireless Power Transfer with One Electric Field Repeater

In this paper, the use of a repeater element between transmitter and receiver capacitive wireless power transfer system for achieving larger distances is analyzed. A network formalism adopted performance described by using three gains usually in context two-port active networks. The analytical expressions as function elements are derived. Assuming that parameters link given fixed, including coupling factors transmitter, receiver, conditions maximizing different acting on terminating impedances (i.e., load internal source conductance) determined. formulas verified through circuital simulations.
