- Abstract
- This paper presents the simplified modeling of near-magnetic field using equivalent magnetic dipole in wireless power transfer. In modeling of magnetic resonators, it is practice to ignore the small volume of the resonator in comparison with the transferring-wavelength and consider it into the magnetic dipole on the ground plane. And this analysis presented here leads to simulated results compare well with full-wave simulation. This approach is useful for the case when the human safety with respect to electromagnetic fields (EMFs) and radio frequency interference (RFI) problems should be considered in the design of wireless power transfer system for high-power applications.
