The resonant mode of the wireless power transmission system is discussed to unveil a mechanism transmission. We have analyzed electro-magnetic resonance phenomenon by using MoM calculate input impedance, port currents, efficiency, and near field distribution. checked that has two frequencies, efficiency maximized at those frequencies. magnetic distribution proves different modes. also considered far find higher frequency better for its high low undesired emission.
