The structure has two working modes, one of them is the working mode, and competition between modes can be easily avoided even when the RF field in the device is very strong compared with the BWO (backward wave oscillator).

• 这种结构主要由调制腔组和换能腔组两部分组成,调制腔组实现电子束速度调制,调制后的电子束在通过一个微波场较弱的区间时实现电子束群聚,然后在换能腔组实现电子能量到微波能量的转化,并通过输出结构输出;
