摘　　要：建立了一种任意截面非均匀波导的直线法分析模型 .以部分介质填充的矩形波导为例对该模型进行了验证 ,结果与有关文献吻合的很好 .对部分介质填充矩形波导中介质片的介电常数和厚度对其色散特性的影响进行了数值计算和分析 ,得到了一些有意义的结果 .本文方法具有推导简便、表达明了、通用性强等优点 ,拓展了直线法的应用范围 .In this paper, an analysis model established with linear method is presented to solve inhomogeneous waveguides with arbitrary cross-section, and the rectangular guides filled with dielectric slab is selected as an example to testify whether the model is credible or not. The analysis result accords with references well. Some useful results are got from the numerical calculation and analysis of rectangular guide filled with dielectric slab about its dielectric coefficient and thickness, which affect the characteristics of dispersion. The analysis model has some virtues such as convenient deduction, clear expression and universal adaptation etc. and the application range of the linear method is expanded.
