周期性结构的边缘元分析

Edge-Element Analysis for Periodic Structures

本文用边缘元、模匹配以及多模网络相结合的方法来分析周期性结构．计算了ＮＲＤ波导周期结构和介质镜象线周期结构两个具体实例．数值结果表明这种方法用于分析周期性结构不仅是有效的，而且具有很高的计算精度和效率．

The periodic strUctures are analyzed by a method in which the edge-element analysis is combined with the mode-matching method and the multimode-network theory. As tWO examples, the NRD gUide Periodic strUctUre and the image line periodic strUcture are calculated with the present method. The numerical resultsindicate that the present approach can be effectively used in analysis for the periodic structares with higher computation accuracy and efficiency.
