General Procedure to Optimize a MIMO Capacitive Wireless Power Transfer System

A general procedure to optimize a multiple-input multiple-output (MIMO) capacitive wireless power transfer system is described, i.e. a configuration with multiple transmitters and multiple receivers. A step-by-step procedure is presented to maximize the system efficiency, by determining the optimal loads and sources. The wireless link is considered fixed, and can be characterized by an admittance matrix, determined by analytical calculations, full-wave simulations or measurements.
