Abstract
In this paper, a novel waveguide made of a hollow
long metallic cylindrical column with a transverse anisotropy
dielectric rod (TADR) is studied. The dispersion relation of
hybrid electromagnetic waves is obtained in this structure,
and its diagram variations will be investigated. The effects of
dielectric permittivity coefficients of TADR on the dispersion
relation of slow waves is studied. The mechanism of wave
generation and its amplification phenomena by a thin annular
relativistic electron beam are investigated for hybrid modes. Also,
the graphs of operating frequency and the graphs of growth
rate will be presented for the waves during the electron beam
injection. The computations have done for terahertz hybrid
waves.
