  • 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-piano 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.
