Abstract :
We developed wireless power transfer system using magnetic resonance, and measured the transmitting efficiency and the electromagnetic fields in the vicinity of system. Then we made comparison between measured filed and the reference level of the ICNIRP guideline. As a results, the similar trend of transmitting efficiency was confirmed with previous studies, and we validated that not just magnetic field but also the electric field is important to evaluate for the exposure assessment in regard to the reference level.
