SAR in human head due to mobile phone exposure

In the present paper, the values of SAR in case of human exposure to mobile phone was determined via different methods. For SAR values determination were studied and compared two case of exposure, one in near field and other in far field. Also it was determined the SAR in human head depending by distance between human head and the mobile phone. The values obtained by numerical simulation using adequate electromagnetic field analysis software such as CST Studio Suite are compared with those obtained by analytical methods for SAR obtained in some cases of the far field exposure.
