traveling wave tubes time-domain simulation finite-difference time-domain method particle- in-cell technic beam-wave interaction
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 calculation results and the test data are less than 6. 1%.
