| Popis: | The interest for GHz frequency range in present wireless communication devices is high. Therefore, a continuous need to observe peculiarities of electromagnetic power deposition in human tissues, when they are exposed to signals in this range, is obvious. In this paper, by using an electromagnetic field simulation software, we aimed to highlight the differences between specific absorption rates (SAR) of energy absorption and their geometric distribution in four cases: at two different frequencies and in two tissue models (plane and anthropomorphic). First step was to design and analyse the electromagnetic field provided by a microstrip antenna, and second step was to compute SAR averaged over 10 g of tissue in two models: a three-layered planar model of human tissues and a homogeneous human head. Similarities and differences are discussed, together with observations regarding temperature increase due to exposures and its trend in different layers of tissues. |
