Abstract

In this paper, the local Specific Absorption Rate (SAR) induced in spherical, cubical, and realistic human head models exposed to a mobile phone is investigated. Three human head models of the highest degree of different shapes but of almost the same volume are considered. Obtained local maximum SAR induced in these three human head models for homogeneous cases are established to have average differences of about 12% and 9% at 900 and 1800 MHz respectively. A comparison analysis of SAR induced in the realistic human head model for homogeneous and inhomogeneous cases are also discussed. From the results, it can be observed that the local maximum SAR induced in the homogeneous human head model is larger than that induced in the inhomogeneous human head model.
