本文提出了一种数值研究，以模拟介质屏蔽的特定吸收率（SAR）和暴露于泄漏微波能量的人体温度升高的影响。在这项研究中，屏蔽的介电性能的影响，在不同的工作频率下的SAR和人体内的温度增加的分布进行了系统的研究。根据所获得的结果，安装的介电屏蔽强烈影响SAR和人体的温度升高。通过设置合适的介电屏蔽体的介电特性，可以同时降低SAR和人体温度升高。电介质屏蔽的适当介电特性在很大程度上取决于工作频率。这些基本数据的辐射防护屏蔽材料的实施，重点是人体组织，以及提供。
This paper proposes a numerical study to simulate the effects of dielectric shield on the specific absorption rate (SAR) and the temperature increase in the human body exposed to leakage microwave energy. In this study, the effects of shield dielectric properties on distributions of SAR and temperature increase within the human body at various operating frequency are systematically investigated. Based on the obtained results, the installed dielectric shield strongly affects the SAR and the temperature increase in human body. The SAR and the temperature increase in human body can be reduced simultaneously by setting the appropriate dielectric properties of the dielectric shield. The appropriate dielectric properties of the dielectric shield greatly depend on the operating frequencies. These fundamental data for the implementations of the radiation protection shielding materials, with focusing on the human organism, are provided as well.
