Slow ionising high-frequency electromagnetic wave along a thin plasma column

Abstract

The problem of the propagation of a slow high-frequency ionising electromagnetic wave along a thin plasma cylinder surrounded by a dielectric tube is considered, assuming that the characteristic diffusion and thermal conductivity lengths are small in comparison with the discharge length. The wave phase characteristics as well as the radial and axial profiles of the wave field and of the plasma electron temperature and density are determined. The obtained results suggest an approach for explanation of the experimental data.
