| 摘 要： | 为了快速分析频率选择表面（FSS），利用天线阵列理论，引入FSS单元之间互导纳的概念，得到互导纳方程。当FSS阵列无限大时，可以应用Floquet定理简化该方程，同时对方程中某些收敛较慢的项进行平面渡展开，利用矩量法求解。采用该思路我们计算了几种多层FSS及多频FSS，并和实测结果进行对比，得到了较满意的结果。不仅如此，该方法相对其他的单一数值方法具有速度快、收敛好的特点。

| Abstract: | In order to quickly analyze frequency selective surface(FSS),that conception of mutual admittance exist within FSS unit is introduced according to the antenna array theory.Then,the relationship between the FSS unit can be described by the mutual admittance equation which is slow convergence.With the assumptions that the FSS is infinite,the equation can be simplified by Floquet theorem,and then it can be solved by the method of moments(MoM).Meanwhile,some parameters of the equation must be simplified with th... |
