Open publisher page 5 citations

Abstract

The human head model is constructed with the help of the High Frequency Structure Simulator (HFSS) software in this paper. The distributions of the specific absorption rate (SAR) in the human head are studied, and then, the influence of the head model dimensions and electrical parameters are discussed. The results show that the absorption of the electromagnetic radiation in the human head is mainly concentrated on the skin and brain tissue, the skull layer absorption is very little. The SAR in the skull and brain tissue increases along with the decreases of the model dimensions. The SAR in the skin increases along with the increase of the electrical parameters. The trends of SAR are more obvious when the head dimensions and electrical parameters were changed at the same time.
