Electromagnetic Wave Scattering From a Thin Annular Magnetized Relativistic Rotating Electron Beam With Dielectric Rod

By using relativistic corrections in dielectric tensor elements of thin annular magnetized relativistic rotating electron beam (TAMRREB), the scattering of a plane wave from the mentioned object, including the dielectric rod, is investigated. The resonance frequencies and their variations versus the geometrical dimensions of the beam, its density, and its rotating frequency are presented. The graphs of the backward scattering cross section and the graphs of polarized charge density on the boundaries of the problem for two different rotating frequencies, for two different plasma frequencies, for two different dielectric constants of rod, and for two different geometrical dimensions are simulated.
