摘　　要：从电磁波的反射定律和折射定律出发,导出了多层介质的近似反射系数。给出了多层介质反射系数与两层反射系数之间的关系。近似反射系数与Maxwell方程组导出的反射系数形式上存在一项差异,分析可知该差异来自于忽略多次反射的假设。最后仿真计算了三层雷达吸波材料(radar absorbing material,RAM)的反射系数,并分析了反射系数随入射角和极化方式的关系。Starting with the law of reflection and refraction of electromagnetic waves, an approximate reflection coefficient of multilayer medium is derived, and the relationship between reflection coefficient multilayer media and two layer of reflection cofficient are given. There is a difference between the reflection approximate coefficient with the one derived from Maxwell quations, which comes from the single reflection assumption. Finally the simulation calculation of three layer radar absorbing material （ RAM, Radar Absorbing Material） reflection coefficient is performed, and the relationship between reflection coefficient versus incident angle and polarization mode is analysised.
