Azimutha lElectromagnetic Surface Waves in a Rod Dielectric Magnetized Plasma Waveguide and Their Excitation by an Anuualar Relativistic Rotating Electron Beam

چکیده مقاله

The dispersion relation of azimuthal electromagnetic surface waves in a rod dielectric magnetized plasma wave guide is obtained. It is investigated that these waves in E-type can be excited by a thin annular relativistic rotating electron beam (TARREB). The effects of the rotating velocity of beam, radius TARREB, on the frequency spectra and growth-rate coefficient are presented.
