摘要
针对多层复合结构的频率选择表面(frequency selective surface,FSS)的应用场合,使用了一种混合算法。该算法结合了矩量法和谱方法的优点,主要通过计算缝隙单元上的感应电压来获得FSS的透波率。对于任意结构的FSS,都可以采用这种思路高效率地得到计算结果。仿真分析了几种复合结构的FSS,并通过实验验证了算法的有效性。最后,用该算法证明了多层介质对于FSS的重要性。
To investigate multiple frequency selective surface （FSS） with composite elements, a hybrid algorithm is presented. The algorithm combines the method of moments （MoM） and the spectral approach, figures out the induced voltage on the element of FSS. Then, the transmission curve of FSS could be acquired. The algorithm could be applied to analyze FSS with any structure efficiently. Some multiple FSSs with composite elements are simulated, and the calculated results show good agreement with the experimental results. In addition, the importance of the multiple dielectric layers is determined.
