Abstract

The aim of this study was to considered possible discrepancy in electromagnetic (EM) fascination in the human head. Commercially available software CST Microwave Studio based on the finite-difference time-domain (FDTD) method was adopted in this study. In this calculation, the conductivity and permittivity of all tissues were increased from 10 to 20% except using if not the same revelation conditions. Familiar cellular phone frequencies of 835, 900, and 1900 MHz were investigated in this research. The rise of up to 20% in conductivity, permittivity and varied substratematerial always caused a SAR variation of 30.42% for SAR 1 g and 23.75% for SAR 10 g at 835 MHz, variation of 22.41% for SAR 1 g and 21.96% for SAR 10 g at 900 MHz and variation of 11.96% for SAR 1 g and 14.29% for SAR 10 g at 1900 MHz respectively.
