对倒同轴矩形槽膜片加载圆波导结构的注-波互作用线性理论进行研究。采用场论的方法,得到了小信号条件下的“热”色散方程。考察了电压,电流及电子注半径对增益和带宽影响。
The linear theory of the annulus - wave interaction of a circular waveguide with inverted rectangular slots is studied. By using the method of field theory, we obtain the “hot” dispersion equation under small signal conditions. The effects of voltage, current and electron beam radius on gain and bandwidth are investigated.
