Evaluation of EMFs to human exposure from wireless power transfer system

In this paper, we investigate electromagnetic fields to human exposure from wireless power transfer (WPT) system based on magnetically coupled resonance method. The resonance frequency, transmission efficiency, and transmitter power is 6.78 MHz, 75 %, and 10 W, respectively. It is shown that magnetic field level around the WPT system exceed the reference level of ICNIRP's guideline.
