摘要

摘要: 基于电子注纵横运动与电磁场纵横分量同时同步相互作用，该文从麦克斯韦方程和线性伏拉索夫方程出发，推导出将回旋共振和契伦科夫共振同时考虑在内的平面单栅注波互作用热色散方程。在合理选择几何参数和电参数的基础上，通过热色散方程数值计算和分析，发现具有回旋共振增强效应下的注波互作用增益和频带都高于只有契伦科夫共振辐射下的结果。

Abstract: Based on the beam wave synchronization interaction in transverse and longitudinal directions at the same time and derived from Maxwell’s equation and linear Vlasov equation, the planar metallic grating beam-wave interaction " hot” dispersion equation considering both cyclotron resonance and Cherenkov resonance is deduced. Through the reasonable selection for geometric and electrical parameters, the numerical calculation and analysis of the " hot” dispersion equation show that the beam-wave interaction gain and frequency band with the cyclotron resonance enhancement effect are higher than those with only Cherenkov resonance radiation.
