Radiation processes in dielectric cylindrical waveguides
A. A. Saharian, L. Sh. Grigoryan, H. F. Khachatryan
Dielectric cylindrical waveguides are widely used for confining and guiding of electromagnetic waves in relatively wide range of frequencies. They have found numerous technological…

Radiation of surface polaritons by an annular beam coaxially enclosing a cylindrical waveguide
A. A. Saharian, G. V. Chalyan, L. Sh. Grigoryan +2
We investigate the radiation of surface polaritons by an annular beam that coaxially encloses a cylindrical waveguide surrounded by a homogeneous medium. By using the Green dyadic,…

Quasidiscrete spectrum Cherenkov radiation by a charge moving inside a dielectric waveguide
A. A. Saharian, S. B. Dabagov, H. F. Khachatryan +1
We investigate the Cherenkov radiation by a charge uniformly moving inside a dielectric cylindrical channel in a homogeneous medium. The expressions for the Fourier components of t…
