层状介质波导中相对论粒子切伦科夫辐射的自放大发射

Self-amplified Emission of Cherenkov Radiation from a Relativistic Particle Inside Layered Dielectric-filled Waveguide

L. Sh. Grigoryan, H. F. Khachatryan, S. R. Arzumanyan

摘要:

结果表明,在某些特殊情况下,带电粒子在填充有半无限介质板和真空间隙的圆柱波导中沿轴向运动时产生的切伦科夫辐射比在填充有半无限固体介质且无真空间隙的圆柱波导中产生的切伦科夫辐射强许多倍。

英文摘要:

It is shown that in some special cases the Cherenkov radiation from a charged particle moving along the axis of cylindrical waveguide filled with a semi-infinite material consisting of dielectric plates alternated with vacuum gaps is many times stronger than that in the waveguide filled with semi-infinite solid dielectric without vacuum gaps.
