| 摘 要： | 基于时域有限差分法在两种电磁辐射源作用下,对人体组织的局部比吸收量分布进行了数值分析计算,并利用三维数值电磁仿真软件对人体局部的比吸收率分布进行了仿真分析计算。结果表明,人体组织对电磁辐射吸收剂量的分布极不均匀,它与辐射频率、辐射强度、暴露时间以及人体组织的导电率、介电常数等多种参数有关。仿真研究表明减少手机表面电流、避开人体谐振频率可以减少人体的比吸收率。

| Abstract: | Based on the method of finite difference time domain (FDTD),the analysis of the distribution of localized specific absorption in human tissues is made under the two electromagnetic radiation sources. In this paper,the imitative analysis and calculation on specific absorption rate (SAR) to the part of human body is achieved,especially head phantom,using 3D numerical electromagnetic computer software. Simulation results show that the distribution of absorption dosage of electromagnetic radiation to human body... |
