本文应用电磁场有限元法分析了双奇异脊波导的传输特性,编程分析计算了不同横截面的双奇异脊波导的主模工作带宽。并比较了脊的尺寸和间距不同时,其主模截止波长和单模带宽的变化规律,得到了相应的数值解。讨论了网格划分对计算结果的精确度的影响。为双奇异脊波导的设计和研究提供了参考。
In this paper, the electromagnetic field finite element method is used to analyze the transmission characteristics of double-odd ridge waveguide. The main mode bandwidth of dual-ridged ridge waveguide with different cross-sections is calculated and analyzed. The change rule of the dominant mode cutoff wavelength and the single mode bandwidth was also compared when the ridge size and spacing were different. Corresponding numerical solutions were obtained. The effect of meshing on the accuracy of the calculation results is discussed. It provides a reference for the design and research of double-odd ridge waveguide.
