Abstract :
The electromagnetic resonance is important candidate of wireless power transfer (WPT) technology for ubiquitous power system. The MIT proposed four-coil WPT scheme based on coupled magnetic resonance. Frequency splitting and critical coupling are shown by distance of resonators. But it is still necessary to assess power transfer characteristics according to various resonator positions.
