摘要: 本文用線性化弗拉索夫-麥克斯韋方程分析了介質(zhì)膜波導中由大迴旋半徑電子束環(huán)產(chǎn)生的迴旋自共振微波激射器的工作特性。結(jié)果表明,介質(zhì)膜能降低所需的電子束能量,在毫米和亞毫米波段開創(chuàng)了一種新型的有效低壓輻射源。

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. -
