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