Modeling EM thermal effects on visible human by a numerical hybrid method

Virtually every citizen is exposed to the electromagnetic fields associated with mobile phones and base stations, radio waves, computers in offices, electrical power lines, and so on. The question is raised as to possible risks and effects of electromagnetic fields. There are possible health risks associated with mobile telecommunication systems. For ordinary discussion on the limit SAR values, people do not consider the irregular absorption of die different parts inside a human body. The database of the virtual Chinese human (VCH) gives the whole blood vessels of the sample human body, which makes it possible to implement the modeling of the EM heating effect exactly and dynamically. A hybrid method is used, in which the EM heating effects inside a human body can be determined by using FDTD numerical method, the numerical model of the heat adjusting system can be set up with theoretical analysis, the flow of the blood can be modeled by the finite element method, and the heat adjusting system of the body can be set up by theoretical and finite difference methods. Finally, the algorithm for implementing the dynamic numerical model of EM heating effects based on the Visible Human Project (VHP) is given.
