Surface waves were studied in cold cylindrical plasmas with axially non-uniform density profiles, and the eigenfrequencies and eigenfunctions for the transverse-magnetic modes of pure and hybrid surface waves were obtained numerically for collisional plasmas. The analysis of the wave equation takes into account the singularity caused by plasma resonance at which the wave frequency is equal to the local electron plasma frequency. It is shown that the axial eigenfunction of the pure surface mode peaks at the position of the plasma resonance layer, whereas the axial eigenfunction of the hybrid surface mode has two peaks at the plasma resonance layer and at the interface of the plasma and a quartz plate. Transverse-electric surface modes in axially non-uniform plasmas without plasma resonance are also analyzed.
