不对称脊波导的传输特性

Transmission Characteristics of Asymmetric Single Ridge Waveguide

提出了用有限差分方法分析不对称脊波导主模的截止波长和场结构图等传输特性,推导出用有限差分方法计算相关参数的公式。脊波导中主模的截止波长可随脊位置的变化而变化。文中编程计算了不对称脊波导、L型波导脊位置变化时截止波长和场结构的变化规律,给出了计算数据和曲线图。计算结果与相关文献非常吻合,证明文中提出的计算方法和计算结果是正确和可行的。

This paper describes the application of finite difference method for obtaining the cutoff wavelength and the field pattern of asymmetric single ridge waveguide, and gives the specific equation for eompu ting related parameters. The cutoff wavelength can be changed by changing the ridge position. The paper computes the cutoff wavelength and field pattern at different ridge positions in asymmetric single ridge waveguide and L-shape waveguide. Some computational data and figures are presented. The results are very closed to ones in related articles, which proves that the method and results are right and feasible.
