摘要: 文中给出了脊峯形同轴波导的各波型的截止频率曲线,与最低波型的功率传输量,还有一个波导的衰耗常数公式,指出了脊峯形同轴波导具有极低的截止频率,可以在很宽的频段内工作。这些是同轴线工作于TEM波型时的特性。
Abstract: Curves giving the cutoff frequencies of some modes and the power carrying capacity of the lowest propagating mode and an equation giving the attenuation constant are presented for a ridge coaxial waveguide. It is shown that the ridge coaxial waveguide has very low cutoff frequencies and rather great higher-mode seperation which also are properties of the coaxial TEM mode.
