摘要
针对有限频率选择表面的电磁散射特性难以用一般方法进行分析的难题 ,提出了两种行之有效的适合不同情况的高效处理方法 :谱域伽略金法和基于平面波谱 (PWS)分解逼近的方法 ,大大节约了CPU的计算时间和内存空间。
Aiming at that it is difficult to analyse the electromagnetic scattering characters of the finite Frequency Selective Surfaces (FSSs) by general ways, two highly efficient means adapted to different conditions are put forward, they are the Spectral Galerkin Method and Plane Wave Spectral (PWS)Decomposition Method. As a result, lots of CPU time and memory requirements are saved.
