Abstract

There has been a heated debate on the harmful bioeffects of mobile phone radiation. In this study, we calculate the SAR in human head under electromagnetic radiation with a simplified model of the human head and the mobile phone antenna based on FDTD algorithm. We then analyze the influence of the frequency of mobile phones and the distance between the antenna and the human head. Our conclusion is that higher frequency and longer distance can possibly reduce danger.

基于时域有限差分算法的手机辐射SAR在人体头部的分布计算
关于手机辐射的有害生物效应一直存在着激烈的争论。在本研究中,我们基于FDTD算法,建立了简化的人体头部和手机天线模型,计算了电磁辐射下人体头部SAR。然后,我们分析了手机频率和天线与人头部之间距离的影响。我们的结论是,更高的频率和更远的距离可能会减少危险。
