Whole-body averaged SAR measurement based on electric field distributions on external cylindrical boundary

The aim of this study is to develop a new whole-body averaged specific absorption rate (SAR) measurement system based on the external-cylindrical field scanning technique. This technique is adopted with the goal of simplifying the dosimetry estimation of human phantoms that have different postures or sizes. An experimental scale model system is constructed. We consider the anatomical European human phantom and plane-waves in the 2 GHz mobile phone frequency band. The measured whole-body averaged SAR results yielded by the proposed method are compared with the results of the FDTD analyses.
