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

Abstract

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 99th 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.
