摘要
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。
The transmission characteristics of double antipodal ridge waveguides are analyzed by finite element method.The domain mode bandwidth for different ridge cross sections of double antipodal ridge waveguides is analyzed by coding.The law of cutoff wavelength of dominant mode and single-mode bandwidth are compared in different ridge dimensions and different space between ridges.We also analyze the influence of mesh divide to the precision of numerical results.These provide reference to the design and research of double antipodal ridge waveguides.
