| 摘 要： | 利用3D电磁仿真软件HFSS中的Master/Slaver边界条件，基于螺旋线慢波结构的角向周期性，提出了一种改进的高频特性仿真方法。将具有3根夹持杆的螺旋线慢波结构的仿真模型从1个螺距的长度缩小到了1/3个螺距。仿真结果表明：采用改进后的模型，计算所得的相关高频特性参数与改进前传统模型所得结果基本一致，但是运算时间减少了至少3/4，且频率越高,计算时间上面的优势越大。

| Abstract: | Based on the angular periodicity of the helix slow-wave structure, an improved simulation method for simulating the high frequency characteristic is proposed using the boundary condition of Master/Slave in the commercial software HFSS. The simulation model for helix slow wave structure with three rods is modified from one screw-pitch to one third. Compared with the simulation results of classical model, the computation time decreases at least 3/4 by the improved model while the results are identical. Morever, the advantage of the improved method will be more evident when the frequency is much higher. |
