摘　　要：　使用MAFIA软件对螺旋慢波线高频特性进行计算模拟,避免解析理论中的假设处理,提高了计算精度,与实验测试值相比色散特性的平均模拟误差为1%左右,耦合阻抗的平均误差为0.2%左右;并对不同建模方法下的不同模拟方法在计算时间和精度上作了比较,证明了准周期边界条件的模拟方法是一种在实际工程应用上同时满足精度与效率要求的模拟方法。The computational simulation for high-frequency characteristic of helical slow-wave circuit using MAFIA software avoids the assumptive theory conditions, improving the calculation precision. Compared with the experiment data, the average error of dispersion simulation result reaches less than 1%, and that of impedance reaches less than 0.2%. Compared with the calculation time and precision using the different simulation method in the different modeling method, the quasi-periodic boundary conditions is proved a simulation method of satisfying precision and efficiency demand in practical engineering application.
