摘　　要：为了克服因增加返波管功率容量而引起的模式竞争问题,提出了波纹内导体同轴慢波结构,导出了该结构在冷腔时的TM0n模式色散方程,并数值计算和分析了该结构的色散特性。分析结果表明:采用该结构的返波管能够很好地改善模式竞争。A coaxial slow-wave structure with corrugated inner conductor is investigated to solve the problem of the mode competition resulting from increasing power capacity of backward wave oscillator. The cold dispersion equation of TMOn mode of the structure is derived. The dispersion characters of the structure are computed numerically, analyzed and compared with that of sinusoidal cylindrical wave guide. The results show that the mode competition is much improved with the suggested new structure.
