Abstract

The transition radiation of charged particle in a regular waveguide of arbitrary cross section filled with anisotropic magneto dielectric plate of finite length is considered. It is assumed that the charged particle crosses the plate perpendicular to the waveguide axis. The wave equations and the analytical expressions for the transverse-electric (TE) field in various regions in the waveguide are obtained. Taking into account the obtained analytical expressions for TE field and using the Poynting vector the energy of transition radiation of moving particle is calculated. The case of rectangular waveguide is considered and the energy of transition radiation is analyzed in this case. The analytical expression of the transition radiation of charged particle for the case of thin plate in the waveguide (the wavelength in the plate is much grater than the length of the plate) is found. The possibility of appearance of Vavilov-Cerenkov radiation is analyzed. The conditions under which occurs the Cerenkov radiation are found. The frequency of Cerenkov radiation is determined too.
