With the wide spread usage of cellular telephones (GSM) in Egypt, many questions have been raised about the influence of these telephones on the human body. In this research, we study the effect of transient electromagnetic fields on the human head using the finite difference time domain technique (FDTD). To develop this study, we have introduced two models for the human head, which are homogeneous and heterogeneous models. These two models have been implemented on two different grid size models, which are the fine model and coarse models in order to illustrate the effect of wavelength to grid size ratio on the accuracy of the results. Three different incident fields have been used to cover a wide band of frequencies. The electric fields inside the head models have been computed and the specific absorption rate (SAR) has also been computed for the proposed models. The SAR results of this work have been compared with international standards, which are the European standard and the ANSI/IEEE standard
