摘　　要：在带状电子束假设下,采用场匹配和导纳匹配的方法,导出了存在电子束的任意槽矩形波导栅行波管的"热"色散方程,对该方程进行数值求解,得到了小信号增益,分别讨论了慢波结构槽形状和电子束参量对小信号增益的影响,为毫米波矩形波导栅行波管的设计提供了理论依据.Under the assumption of the sheet-beam, the ＂ hot＂ dispersion equation of the arbitrary groove rectangular waveguide grating traveling wave tube （TWT） loaded with an electron beam was derived by making use of the field matehing method and admittance-matching method. The numerical results were given by solving the dispersion equation and the small signal gain curve was derived. Finally, the influences of electron beam parameters and groove-shapes of the slow wave structure on the small signal gain were discussed, respectively. The results presented in this study provide theoretical basis for designing the millimeter wave rectangular waveguide grating TWT.
