Electromagnetic Radiation in Bio-Tissue: A Numerical implementation

Wireless personal communication is a rapidly expanding sector, particularly in the field of wireless local area networks. In an indoor wireless network system, an user can be close to the radiating antenna. Therefore, it is important to consider possible health hazards due to this type of exposure. This paper presents an approach to estimate and evaluate the main characteristics, i.e., Specific Absorption Rate and temperature rise, related to human exposure to electromagnetic field radiated by common wireless devices such as Wireless Access Points or Hot-Spot. The assessment is done numerically using two different approaches, respectively Ray-Tracing model and Finite Element Method. The general goal is to provide an efficient and accurate method to assess human head exposure to electromagnetic fields at a frequency of 2.45 GHz and for different types of exposure conditions.
