Power maximization for a multiple–input and multiple-output wireless power transfer system described by the admittance matrix

This paper analyses a multiport wireless power transfer system described by its admittance matrix. The general case of a link using a multiple–input and multiple–output configuration is solved by determining the optimal loads for maximizing the total power delivered to the loads. As a specific application of interest of the proposed theory, a wireless link based on capacitive coupling is analysed.
