研究目的
To evaluate exposure in a human body close to wireless power transfer (WPT) systems by proposing a numerical approach that fully takes into account the EM coupling between a human body and WPT systems.
研究成果
The proposed method is efficient for numerical dosimetry of WPT systems when the human body is situated in their vicinity, as demonstrated by the analysis of a WPT system close to a dielectric cube and numerical dosimetry of a human body close to the WPT system.
研究不足
Not specified
1:Experimental Design and Method Selection:
A hybrid method combining method of moments (MoM) and finite-difference time-domain (FDTD) method is proposed.
2:Sample Selection and Data Sources:
A dielectric cube and an adult male model (TARO) are used.
3:List of Experimental Equipment and Materials:
Not specified.
4:Experimental Procedures and Operational Workflow:
The method involves an iterative computation of MoM and FDTD method, using polarization currents as a source for calculation of scattered EM fields.
5:Data Analysis Methods:
The convergence of the FDTD solution is found using an approach instead of the conventional peak-search method.
