摘　　要：用直线法对几种典型规则波导的截止波数进行了计算和验证,并以茧形波导为例,对其传输特性进行了数值计算和分析,并将二维电磁场边值问题扩展至任意形状截面。In this paper,an analysis model by using the method of lines is presented to solve wave-guide with arbitraty cross-section.Cut-off wave number of several typical regular wave-guides is calculated and the results are testified credible.Cocoon wave-guide is selected as an example,numerical calculation and analysis of its transmission characteristics are done at the same time.So the 2-D boundary value pro-(blems) of electromagnetic are extended to arbitrary cross-section.The analysis method has some advantages such as easy formulation,less computation and universal adaptation etc.
