| 摘 要： | 为了解决结构型吸波材料的分析和设计中所遇到的反射系数计算问题，从电磁场理论出发，导出了电磁波以任意角入射时多层雷达吸波材料（RAM）涂层的反射系数公式，此法简单易行，为结构型吸波材料的计算机辅助分析和设计提供了基础，同时给出了计算曲线的例子，通过实例计算分析了电磁波的入射角，极化状态等对反射特性和隐身效果的影响。

| Abstract: | To solve the computing of reflecting coefficient in the analysis and design of structural absorbing materials, the formulae of reflecting coefficient are derived from the theory of electromagnetic field for incident electromagnetic wave to multi-layer radar absorbing material (RAM) coat. This method is easy and can provide a basis for CAA and CAD of structural wave-absorbing material composition. An example for calculable curve is presented, influence of incident angel and polarization state on reflecting and stealth effect are analyzed by means of numerical calculation. |
