摘要

本文研究了带调制各向异性填充的垂直于波导轴线运动的源(带电粒子)的跃迁辐射。特别注意这种辐射在“强”相互作用区域的特征。考虑到调制深度小，在上述区域内计算了波导中TE场的跃迁辐射能量。结果表明，在一定条件下，切伦科夫辐射可以在强相互作用区域产生。

Transition Radiation in a Waveguide Filled with Periodically Modulated Medium

The article is devoted to the study of the transition radiation of the source (charged particle), which moves perpendicular to the axis of the waveguide with modulated anisotropic filling. The special attention is given to characteristics of this radiation in the region of “strong” interaction. The transition radiation energy for the TE field in the waveguide is calculated in the above-mentioned region in view of small modulation depths. It is shown that under certain conditions Cerenkov radiation can arise in the region of strong interaction.
