| 摘 要： | 为了研究倒梯形对称双脊波导脊的结构参数变化对传输特性的影响,在MATLAB环境下应用有限元工具箱PDE进行二次编程,计算了倒梯形对称双脊波导在TE模式下的截止波长和单模带宽,分析研究了倒梯形对称双脊波导截止波长和单模带宽随结构参数的变化。数值结果表明,与相同条件下矩形、梯形脊波导比较,倒梯形脊波导的单模带宽较宽,截止波长最大。

| Abstract: | In order to study the effect that the change of anti-trapezoid ridge waveguide with symmetric-double-ridge has made to transmission characteristics,the secondary programme has carried out with the help of partial differential equation toolbox(PDEi)n the condition of Matlab.It has calculated the anti-trapezoid ridge waveguid′s the cut-off wavelength and single-mode bandwidth in TE mode when the ridge change.From these,it has analyzed that the cut-off wavelength and single-mode bandwidth has changed along wit... |
