Dosimetry Analysis of A 3-D Open-Structured Wireless Power Transfer System

This paper provides a dosimetry model of a 3 dimensional (3-D) box-shaped open-structured wireless power transfer (WPT) system for mobile devices. The induced electric field in the forearm and hand of an adult male model are evaluated at 6.78 MHz with 99
^th
percentile values as prescribed by ICNIRP. Numerical method of scalar potential finite difference (SPFD) is adopted for the dosimetry analysis; different positions of the forearm with respect to the charging system are investigated. This paper presents an explicit dosimetry model and analysis of the electric field in human forearm for a 3-D box-shaped WPT system.
