本文计算了直角皱纹脊波导慢波主通带上下二端的截止频率,给出了上下截止频率随尺寸变化的一组曲线。在九个试验样品上做了实验研究,理论和实验值吻合较好。本文后部分给出了沿皱纹脊波导壁横向场分布的测试图。文中还讨论了尺寸对色散特性的影响、场分布的频率特性以及皱纹脊波导的特点等。
In this paper, the cut-off frequencies at the upper and lower ends of the slow-wave main passband of a right-angle corrugated ridge waveguide are calculated, and a set of curves of the upper and lower cutoff frequencies with the size changes are given. Experiments on nine test samples were done, and the theoretical and experimental values agree well. In the later part of this paper, a test plot of the transverse field distribution along the corrugated ridge waveguide wall is given. The paper also discusses the effect of size on the dispersion characteristics, the frequency characteristics of the field distribution and the characteristics of the corrugated ridge waveguide.
