| 摘 要： | 用阶梯近似的方法分析任意槽形加载的圆波导慢波系统中的场,采用自洽场理论,得到了任意槽形周期加载圆波导慢波系统在小信号条件下的“热”色散方程,并对结构参数对小信号增益的影响情况进行了研究。加载深度和槽口宽度在固定频率下都有一最佳值使得增益最大。

| Abstract: | The profile of arbitrary shaped groove is approximated by a series of rectangular steps and the "hot" dispersion equation of the coaxial arbitrary-shaped-groove slow-wave structure is derived by the self-consistent theory.The influence of structural parameters on the small signal gain shows that,to achieve the maximum gain,both the depth and the width of the groove have an optimal value at a fixed frequency. |
