Abstract

We present results from numerical calculations performed for a surface-wave discharge (SWD) sustained in neon at atmospheric pressure using a two-temperature fluid model. We determine the phase characteristics of the wave as well as its attenuation characteristics. The attenuation fully determines the axial structure of SWDs. We obtain the spatial distributions of plasma parameters (gas temperature, electron temperature, electron density) and of the intensity of electric field components. The calculated axial distributions of the radially averaged plasma parameters are compared with experimental results taken from the literature and from our measurements. A satisfactory agreement is found.
