Abstract: The discharge mechanism of the atmospheric-pressure waveguide-based microwave plasma is investigated experimentally by considering the role of the discharge tube. When the radius of the aperture holes on the wide waveguide walls is equal to that of the thin-walled discharge tube, the plasma is induced in an equivalent resonator with a certain Q value, presenting a torch-like plasma. However, if there is a launching gap of enough interspace between the aperture holes and the discharge tube, a surfaguide plasma can be developed at atmospheric pressure.
