Abstract: Impedance matching is implemented to stabilize an atmospheric-pressure waveguide-based N-2-Ar plasma torch with the aid of the use of swirl gas. Optical emission spectroscopy is employed to diagnose the plasma torch with respect to the population of the electronic state N-2(+) (B (2)Sigma(+)(u)) and N-2(B (3)Pi(g)) versus the absorbed power and the ratio of N-2 component in the Ar-N-2 mixture by the measurement of the emission of intensity. The qualitative discussion based on the reaction routes is delivered to interpret the experimental results well.
