Research and Analysis of Human Brain and Electromagnetic Radiation SAR Based on HFSS

摘要

In the development of wireless communication technology, the transmission efficiency is increasing while the electromagnetic radiation is increased. The harm of electromagnetic radiation to human body has been a research hot. In order to measure the radiation for the human brain from electromagnetic radiation when using the hand-held mobile terminal, a new measurement method is proposed that design and simulate the model made of hand-held mobile terminal and human brain with HFSS software, then record some parameters from SAR(specific absorption rate) curve, electric field intensity distribution and magnetic field intensity distribution after simulation. The simulation results show that the parameters of electromagnetic radiation SAR are much higher than international standards when the human brain and hand-held mobile terminals are paste to each other but when the distance increases gradually it appears the nonlinear decreasing trend.
