| 摘 要： | 人体这个局部的电磁兼容系统，正面临着环境电磁骚扰的挑战。为了更加深入的理解电磁波生物效应，文章通过对人体构建三层介质模型，利用解析法研究了电磁波垂直入射到人体模型时，在几层介质内的能量损耗状况；入射与透射电磁波之间的关系；给出了入射系数与反射系数的表达式。最后根据具体的电磁环境进行了讨论，并计算了比吸收率。

| Abstract: | The human body,a partial electromagnetic compatibility system,was facing the harassment challenge of environmental electromagnetic waves.For the more thorough understanding of electromagnetic wave biological effect,this article constructed three media models of the human body,and discussed the energy loss conditions in several media,the relations between the incident and refracted electromagnetic waves,and then worked out each layer's theoretical expressions of reflect and transmit's coefficient by using analytical method.Finally,the concrete electromagnetic environment was discussed,and the result of specific absorption rate was given in this paper. |

| Keywords: | Three media manikin Electromagnetic wave Reflectivity and transmissivity Poyntings' Vector Specific absorption rate |
