Undesired emission from magnetic-resonant wireless power transfer

摘要

Undesired emission from magnetic-resonant wireless power transfer is discussed. At first, we investigate resonant mechanism by using MoM simulation. We elucidate that there are odd mode and even mode resonance, which are modeled by two electric dipoles excited in-phase and out-of-phase, respectively. Next, we calculate effective isotropic radiation power (EIRP) for odd and even mode frequencies. We unveiled that the EIRP for even mode is 18dB smaller than odd mode.
