【摘要】 提出了一种角向周期结构静电电子回旋脉塞的方法。用流体线性理论导出了这种脉塞的色散方程和增长率公式,并进行了相应的分析与计算。此结构能较好地克服正常同轴波导静电电子回旋脉塞工作频率难以提高的困难,并且该结构中的多种角向梯式时提高工作频率和电子注效率是一个良好的途径。更多还原

【Abstract】 Presents a new scheme of the electrostatic electron cyclotron resonancemasers(EECRMs)with azimuthal periodic structure.The dispersion equation,the radia-tion frequency and growth rate formulae are derived by using the linear fluid theory.Having studied them analytically and numerically,it is found that the difficulty to increasethe radiation frequency in the EECRMs with general coaxial waveguide can be overcome,and two kinds of azimuthal modes in this structure offer the way to increase the radiatonfrequency or to enhance the electron efficiency.更多还原
