Abstract

The purpose of this paper is to investigate the induced SAR in an inhomogeneous model of human body for exposure to EM wave from a dipole antenna at 400 MHz. Two positions of the antenna are considered, that is, those behind the back and waist of the human body. In particular, we compare the results obtained with the homogeneous and inhomogeneous models. As a main result, a large difference in the SAR distribution is observed between two models. Additionally, the peak SARs averaged over 1g or 10g of tissue obtained using the homogeneous models are overestimated as compared with those obtained by the anatomical model, only when the antenna-model distance is small
