|Abstract:||This paper presents 3D finite element analysis for heat transfer and specific absorption rate of electromagnetic field in human body at 915 MHz and 2.45 GHz. The purpose of this research is to study the effects and harmfulness of leakage electromagnetic field to organ in living tissue. We propose a simulation of microwave radiation by using a finite element method (FEM) to our system for studying heat transfer and specific absorption rate of electromagnetic field in multi-organs living tissue. Electromagnetic wave distribution source in our system was designed as a microstrip 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 , specific absorption rate (SAR) and temperature. The SAR value will be followed the standard of ICNIRP (1998) and the results at 915 MHz and 2.45 GHz shown that maximum temperature in organs are different if frequencies different, in 3D model can be obtained every point of view and benefit for development protection system in near future. ©2012 IEEE.|
