Abstract
Previous studies on the influence of transverse plasma-density nonuniformity and collisions on the propagation of electromagnetic surface waves along plasma columns are extended to magnetized-plasma cases of Trivelpiece-Gould modes. The analysis based on numerical results concentrates on situations of moderate axial magnetic field strengths where similarities to unmagnetized cases remain, though modified and reduced with growing magnetic field. Combined effects of collisions, radial plasma-density inhomogeneity and degree of plasma magnetization on the propagation properties of the waves are emphasized. The resonances in the radial field distribution, which occur as long as the wave frequency can match the upper hybrid frequency in the radial density profile are discussed.
