摘　　要：考虑非翼片区角向高次模式以及螺带厚度,运用场匹配方法参考脊加载环板慢波结构的边界条件推导得到翼片加载螺旋慢波结构的色散特性方程;并运用MAFIA软件对该结构进行模拟计算,将理论结果与模拟计算进行比较,其误差范围基本满足设计精度的要求,并讨论了不同翼片结构参数对色散特性的影响,为各种类型的翼片加载螺旋慢波特性的计算提供了一种参考方法.Considering azimuthal higher order modes in non-vane area and helical tape thickness, using field matching method and boundary condition of the ridge-loaded ring-plane slow wave structure, the dispersion equation of vane-load helical slow-wave structure is obtained. The numerical simulation for the vane-loaded helical slow-wave structure using MAFIA software is done. The theory calculation results are compared with the simulation results. Their errors reach the request of design precision. The effect of the dispersion is discussed in the different parameters of the vane structure. The instruction method also is provided for other types vane-load helical slow-wave structure.
