摘要: 本文用线性化弗拉索夫-麦克斯韦方程分析了介质膜波导中由大迴旋半径电子束环产生的迴旋自共振微波激射器的工作特性。结果表明,介质膜能降低所需的电子束能量,在毫米和亚毫米波段开创了一种新型的有效低压辐射源。Abstract: The characteristics of the cyclotron autoresonance maser with a large-orbit electron ring in a partially dielectric-loaded waveguide have been analyzed by making use of the linearized Vlasov- Maxweil equations. The results show that the dielectric liner can reduce the energy of ekctron beam, and a novel radiation source can be made in the millimeter and submilimeter waveband by using this method.
