摘要

近年来,无线通信领域出现了爆炸性增长,到2000年,全世界预计将有数亿用户拥有移动电话。随着这些手机的普及,人们对电磁场与生物组织的相互作用产生了疑问,特别是对人类头部吸收的能量产生了疑问。本文采用有效的数值方法计算了天线头部的局部吸收功率,并预测了由于天线与头部的紧密耦合而导致的天线性能的变化。

The analysis of human head interaction with a hand-held mobile using the non-uniform FDTD
Recent years have seen an explosive growth in the area of wireless communication and, around the world, several hundred millions of subscribers are expected to have mobile phones by the year 2000. With the proliferation of these phones, questions have arisen about the interaction of the electromagnetic field with biological tissues in general, and about the power absorbed by the human head in particular. In this paper we employ efficient numerical techniques to compute the local absorbed power in the head and to predict the modification of the antenna performance due to its close coupling with the head.
