In this paper, we present the modeling results of electromagnetic fields in medium with dielectric properties (permittivity and conductivity) similar to biological tissues, by developing a computer code by Finite Differences Method (FDTD). These simulations allowed the deduction of specific absorption rate (SAR) as the quantity absorbed by the human head near a mobile phone for two frequencies GSM 900 MHz and 1800 MHz.
