Gas discharge sustained by the nonpotential symmetric surface wave in magnetized heterogeneous plasma column

This report is devoted to research into the dispersion properties, damping rates and radial wave field structure for electromagnetic azimuth-symmetric high-frequency surface waves (SWs) in a radial inhomogeneous cylindrical waveguide structure with given plasma density radial profile. The dependence of the plasma density axial profile in the discharges sustained by the considered SW in a diffusion controlled regime from the plasma heterogeneity was also studied. The external steady magnetic field is directed along the axis of the waveguide system. The plasma is considered in hydrodynamic approximation as a cold and weakly collisional medium with a constant value of the effective electron-neutral collision frequency for momentum transfer. The axial structure of the SW sustained gas discharge was studied for the case when the SW characteristics and axial electron density vary slightly along the discharge length
