摘要
基于多层吸波材料的反射率等效电路理论计算模型,采用MathCAD对嵌入频率选择表面(FSS)前后的双层吸波材料的吸波性能进行了计算模拟,并与实际测量结果进行了分析比较。结果表明,吸波材料中嵌入频率选择表面后,吸收频带得以增宽,吸波性能得以改善;利用MathCAD进行计算模拟可以简化编程,并能有效预估吸波材料的吸波性能,从而提高设计制备吸波材料的效率。
In this paper, based on the equivalent circuit theoretic model for reflectivity calculation of multilayer absorbing materials, MathCAD software was used to simulate the reflcctivity of double-layer absorbing materials with or without frequency selective surface （FSS） embedded in. Comparison and analysis have been made between the results of simulation and measurement. Results show that the absorbing bandwidth is enlarged and its absorbing capability is enhanced by embedding FSS in absorbing materials; moreover, the programming process can be simplified by using MathCAD software, and the pro-estimate of the absorbing capability of the absorbing materials can be got. Therefore the efficiency of absorbinz material design and manufacture is imnroved.
