Study on impedance matching and maximum wireless power transfer efficiency of circuits with resonant coupling based on simplified <i>S</i>-matrix

Access this Article



<p>In this manuscript, the simplified <i>S</i>-matrix of the pair of <i>RLC</i> circuits with resonant coupling at the resonant frequency is revealed. All of the elements of the <i>S</i>-matrix (<i>S</i>-parameters) are expressed by using essential quantities, which are the port-impedance/resistance ratios and the <i>kQ</i>-product. The matching condition and the maximum power transfer efficiency are analytically derived from the elements of the simplified <i>S</i>-matrix.</p>
