Simulation Bio-effects of Electromagnetic Field in human body at Microwave Frequency with 3D Finite Element Method

摘要

This paper presents 3D finite element simulation of Bio-effect and SAR electromagnetic field in human body at 2.45 GHz. In this paper, we would like to study the Bio-effects and harmfulness from leakage electromagnetic field to organs in living tissue. We propose a simulation of microwave radiation by using a finite element method (FEM) to our system for studying SAR of electromagnetic field in multi-organs living tissue. Electromagnetic wave distribution source in our system was designed as a micro strip type and placed at 5 cm from multi-organs living tissue model. As a preliminary, leakage power was assumed at 100 W and exposure time was 1800 s. The result from finite element method show distribution of electromagnetic field in 3D air space of multi-organs tissue model, SAR and temperature. The SAR value will be follow the standard system and the results at 2.45 GHz the results shown that maximum temperatures in organs are different if frequencies different, in 3D model can be obtain every point of view and benefit for development protection system in near future.
