摘要

In this study, we discuss human exposure to electromagnetic fields from magnetically coupled resonance wireless power transfer system operating at 1.8 MHz. A two-step method that is composed of the finite element method (FEM) and finite-difference time domain method are proposed. The applicability of the proposed two-step method for a localized exposure within this frequency band is discussed by comparing the specific absorption rate (SAR) in a homogenous human-body model computed using the FEM. From the computational results, the difference between the peaks 10-g averaged SAR is below 10 %. These suggest results that the proposed method is applicable for evaluating compliance in realistic anatomical human body models from a wireless power transfer system. With proposed two-step methods, the SAR in the anatomical human body model is computed for the different exposure scenarios under isolated and grounded conditions. The peak 10-g averaged SAR in grounded human is larger than that in an isolated human. In the worst case, the peak 10-g averaged SAR for isolated and grounded condition are 50.6 and 60.7 mW/kg, respectively. The peak 10-g averaged SAR limits are generally reached when the input powers are 33 W for the worst-exposure condition. (C) 2015 Wiley Periodicals, Inc.
