SAR of the human's head due to electromagnetic radiation of a mobile antenna

In this paper, the influence rate of mobile phone radiation on the human head near the mobile antenna that is in various angles relating to the human head will be presented. To compare the results, we use SAR (Specific Absorption Rate) that is the indicator of the amount of absorbed RF wave's energy by human's tissues. In order to observe the effect of changing the angle of mobile antenna relating to the human head, we continued the simulation, at first being parallel the antenna with the neck that indicate 0° and after that by increasing 10° the angle of antenna relating to human head in each step, to 90° angle that the antenna is along the neck.
