| 摘 要： | 为了对螺旋线行波管注-波互作用这一复杂物理现象进行快速的实时跟踪模拟与分析,采用T型有耗L.Brillouin模型,有机结合时域有限差分方法(Finite-Difference Time-Domain,FDTD)与粒子模拟(Particle-In-Cell,PIC)技术,建立了行波管的非线性互作用计算体系。在此基础上,采用C语言自主研发了运行稳定的计算程序。应用这一研究成果,对某支成熟管型的行波管开展模拟研究,增益模拟结果与实测数据的偏差小于6.1%。

| Abstract: | To track and simulate the complex physical phenomena of beam-wave interaction of helix Traveling Wave Tube(TWT) fast and in real-time,a nonlinear interaction computing system is established by improving the T type loss L.Brillouin model and taking the finite-difference time-domain method and the particle-in-cell technic as core means for numerical solution.Based on this,a steady C program is developed.Through running the program,a mature TWT is simulated and the differences between the output gain calculati... |
