给定厚度RAM涂层材料参数优化

Parameter Optimazation of RAM Under a Given Coating Thickness

本文从涂层金属表面反射系数表达式入手，探讨了给定吸波涂层厚度时，雷达吸波材料（ＲＡＭ）电参数与涂层表面反射系数间的内在联系，导出反射系数取极限值时涂层材料参数所满足的非线性方程组。以数值分析为手段，利用上述关系实现了给定厚度涂层材料电参数的优化。

With the help of reflection coefficient formula of conductor coated with RAM layer,therelationship between the RAM parameters and the surface reflection coefficient of a RAMcoating conductor is discussed,and the non-linear equations are derived out with which theRAM parameters should satisfy when the reflection coefficient arrives at a limit value. Alsoin this paper,numerical analysis method is used to obtain a set of optimal pararneters undergiven thickness.
