Analysis for transmission characteristics of groove guide with arbitrary cross-section by using the method of lines

用直线法对任意截面槽波导进行了分析,对几种典型槽波导的传输特性进行了数值计算和分析比较,并将本文分析模型与相关文献进行了对照,误差在1%以内．提出了一种新型截断圆形槽波导,并对其传输特性进行了数值计算和分析．

The groove guide with an arbitrary cross-section is analyzed in this paper by using the straightline method. Several typical groove guides are exemplified, their transmission characteristics are numerically calculated, analyzed and compared. And compared with some relative references, the calculated errors in this paper are within 1%. A new type of truncated circular-groove guide is proposed and its transmission characteristics are also numerically calculated and analyzed. It is of certain reference value for studying and engineering application of groove guides.
