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…
Fermionic Casimir densities for a uniformly accelerating mirror in the Fulling-Rindler vacuum
A. A. Saharian, L. Sh. Grigoryan, V. Kh. Kotanjyan
We investigate the local characteristics of the Fulling-Rindler vacuum for a massive Dirac field induced by a planar boundary moving with constant proper acceleration in -di…
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…
Surface polariton excitation and energy losses by a charged particle in cylindrical waveguides
A. A. Saharian, L. Sh. Grigoryan, A. S. Kotanjyan +1
We investigate the emission of surface polaritons (SPs) by a charged particle moving inside a dielectric cylinder parallel to its axis. It is assumed that the cylinder is immersed…
Coherent radiation from a chain of charged particles on a circular orbit around a dielectric ball
L. Sh. Grigoryan, A. H. Mkrtchyan, S. B. Dabagov +5
We investigate the electromagnetic radiation from a chain of relativistic charged particles uniformly rotating along equatorial orbit around a dielectric ball. For weak absorption…
