Abstract

The mode competition problems in a gyro-TWT were investigated by a nonlinear steady-state multimode theory. Simulation results show the effect of backward wave oscillation mode (TE₂₁⁽²⁾) and working mode (TE₁₁⁽¹⁾) on each other for different beam current and guiding center radius, which helps to discuss how to suppress the oscillation and improve the amplification characteristics.

用稳态多模理论分析陀螺行波管的后向波振荡

利用非线性稳态多模理论研究了陀螺行波管的模态竞争问题。仿真结果表明，在不同的光束电流和导向中心半径下，后向波振荡模式(TE21(2))和工作模式(TE11(1))相互影响，有助于探讨如何抑制振荡和改善放大特性。
