摘　　要：利用线性场理论导出了周期性波纹波导中电磁波传播的色散方程.通过数值计算和用谐振法冷测,分别得到了周期性波纹波导的色散特性,分析表明,理论计算与实验结果吻合.A high frequency electromagnetic system is a main part of a microwave tube. Its characteristics and parameters can directly influence the most technical index of a microwave device. As an important slow wave system, a corrugated-wall waveguide has been applied to a high power microwave device such as a relativistic traveling wave tube or backward wave oscillator. By means of linear field theory, the dispersion relation of the corrugated-wall waveguide is derived. The dispersion characteristics of the periodic corrugated-wall waveguide are achieved, respectively, by means of numerical calculation and resonance measure. On the basis of the analysis, it is found that the two results tend to be identical.
