Guided electromagnetic modes along a homogeneous circular column of plasma imbedded in free space are examined for the two extreme cases of zero and large axial magnetic field. The plasma is assumed to be cold and collisionless and ion motion is neglected. The assumptions made are approximated by certain laboratory plasmas and hence the results may be of practical importance. For the zero field case the modes with azimuthal variation are found under certain conditions to exhibit backward wave characteristics and previously published results of a quasi-static analysis are modified. In the case of large magnetic field, the occurrence of unique wave guiding features is discussed.
