In gyro-traveling-wave devices, several waves can be excited at different cyclotron harmonics simultaneously. This paper analyzes the interaction between three waves synchronous with gyrating electrons at different cyclotron harmonics in two relativistic gyro-amplifier configurations; viz., gyro-traveling-wave tubes and gyrotwystrons. Two types of nonlinear interactions are considered: (a) excitation of two waves at cyclotron harmonics by a wave excited at the fundamental resonance, and (b) excitation of a wave at the fundamental resonance and another wave at the third harmonic by a wave excited at the second cyclotron harmonic. The effect of the overlapping of electron cyclotron resonances on the performance of relativistic gyrodevices is investigated as well.
在回旋行波器件中，可以同时在不同的回旋谐波上激发多个波。本文分析了在两种相对论性回旋放大器结构中，与回旋电子同步的三个波在不同回旋谐波上的相互作用；即回旋行波管和回旋速调管。考虑了两种非线性相互作用：(a) 在基波共振处激发的波在回旋谐波上激发两个波，以及 (b) 在二次回旋谐波处激发的波在基波共振处激发一个波并在三次谐波处激发另一个波。还研究了电子回旋共振重叠对相对论性回旋器件性能的影响。
