Abstract :
Summary form only given. A theoretical investigation of a plasma torch generated by a surface wave sustained discharge operating at 2.45 GHz at atmospheric pressure conditions in N2-Ar mixture is presented. The main plasma and wave characteristics are obtained in the framework of a self-consistent theoretical model accounting for the main discharge balances. The dependence of the axial profiles of the gas temperature and electron density on the mixture composition, gas flow and power delivered to the launcher is analyzed. Theoretical results for wave electric field spatial distribution are compared with experimental data
