Numerical Modeling of the Interface between Source RF and the Human Body

We want to write a very important part of our research by a presentation with a numerical method, which aims to solve the electromagnetic radiation effects of radio frequency source on the human body. With other words, what are the effects of the use of mobile phone on human tissue, and specifically the human head, with choosing the best interface between the mobile and the latter? Therefore, our problem is the electromagnetic field coupling between the radio frequency power source and the biological tissue (human head). To solve this problem, a system of equations placed and the choice of formulation of finite elements that coupled with the boundary integral formulation that adopts with the system. A call to the numerical modeling gives results which shows the connection between the characteristics of the exterior medium (σ,e,m) and the electromagnetic field of the RF source in the interior medium (human head). With this method we can assess the RF energy at each point of the interior medium (human head), basing on the parameters of the exterior medium, we are able to choose the best material of the interface's realization.
