本文提出空域积分方程法分析周期性结构。空域周期格林函数的计算通过改进的Ewald变换进行加速。利用周期性结构栅格的对称性简化了几何模型的尺寸，未知量大大减少，以致填充矩阵和求解MoM线性系统的时间大为减少。我们的方法跟目前已发表的文章和商业软件相比，更高效和精确。

In this paper,we present a space-domain integral-equation method for the analysis of period-ic structures formed by three-dimensional (3-D) metallic objects arranged in a general skewed two-dimensional lattice. The computation of the spatial domain Green’ s function is accelerated by the Ewald transformation. The geometric model is simplified by the lattice symmetry,so that the unknown is greatly reduced. Filling MoM matrix and solving linear system are greatly reduced. Our technique shows much higher efficiency when compared with available commercial software and the methods published at pres-ent.
