Abstract

Distribution of the roots of dispersion equation of the parametric Cherenkov radiation (PCR) excited by uniformly moving charged particle in an ideally conducting metal waveguide filled with a spatially periodic layered dielectric is studied. The study both in long wavelengths range and in the range of wavelengths comparable and smaller than the period of non-uniformity is presented. It is shown that in the case of long wavelengths the dependence of the frequency of the excited PCR on the particle velocity is monotonic. For the case of wavelengths comparable and shorter than the non-uniformity period the spectrum of PCR is more complicated. Its characteristic features are determined.
