✦ Synopsis

A theoretical model of plasma source based on azimuthal surface waves (ASW) propagation in a plasma filled cylindrical metal waveguide is presented. The ASW propagate across an external axial steady magnetic field and posses the eigenfrequencies in the range between upper hybrid frequency and the cut-off frequency for HF bulk wave. The problem is studied using a local hydrodynamic approach and taking into consideration a collisional wave damping. Spatial distributions of the ASW fields and produced plasma density are examined both analytically and numerically.
