Study of the Thermal Effects Caused by EM Radiation for Human Models

It is important nowadays to study how to influence Personal Communication System’s EM radiation on human, to avoid their adverse impacts. While it is known that there are two kinds of effects caused by the EM field: biological and thermal, only the thermal effects (when fields produce greater heating-temperature rise in human tissue) have been considered in this paper. The motivation of this work is to evaluate temperature rise and distribution for a child’s and a woman’s head models, also its important to determine SAR distribution. The non-homogeneous discreet models of a child and a woman were used for simulation. The dipole antenna of λ/4 length located at 10mm distance from the head models. The simulations have been conducted at 300MHz, 1900MHz and 3700MHz frequencies using the EM and thermal solver FDTDLab. These frequencies have been selected due their use in everyday life, 300MHz for radio communications, 1900MHz for GSM networks and 3700MHz for other wireless communications and future basebands.
