The dispersion relation of azimuthal electromagnetic surface waves in a rod dielectric magnetized plasma waveguide 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.
