摘要

文章利用亥姆霍兹方程的有限差分格式

研究了在新型单脊矩形波导中

脊在中心位置且几何尺寸变化时对传输特性的影响。计算了脊的尺寸变化时的截止波长cλ和单模带宽B（cλ/cλ1）

并给出了TE10和TE11模式的场结构图以及变形对截止波长和单模带宽影响的相应曲线。通过与传统单脊矩形波导的对比

指出了新型单脊波导传输特性的优缺点。

Abstract

Using finite-difference method for the Helmholtz equation

this paper investigates the influence of the ridge in a novel single-ridge rectangular waveguide on the transmission characteristics of the waveguide when the ridge is in the central part and its dimensions vary.It calculates the cutoff wavelength λc and single-mode bandwidth B（λc /λc1） when the ridge dimensions vary and gives the field patterns of TE10 mode and TE11 mode and the curve corresponding to the relevant effects of the transfiguration.By comparing with the conventional waveguide

it points out the advantages and disadvantages of the new single-ridge rectangular waveguide.
