用时域有限差分（FDTD）法分析了非对称单脊波导部分几何尺寸变化对主模带宽的影响，结果表明，可以通过改变脊波导的部几何分尺寸来调节单模带宽。实例计算了对称单脊波导的截止波数，并与文献报道的结果进行比较，结果显示利用该计算方法所得数据精确有效。

The influence of the geometry size on the bandwidth of the dominant-mode in an asymmetric single ridged waveguide is analyzed with the finite-difference time-domain （FDTD） method. Numerical results demonstrate that the bandwidth of the dominant-mode can be regulated by changing the geometry size of the waveguide. The wavenumbers of the symmetric single ridged waveguide are given to validate the theory, and to demonstrate the degree of its efficiency.
