Description
The advantages of the atmospheric pressure microwave plasma jet (MPJ) over the previous and conventional methods make it a potential system for certain industrial material processes. This paper presents the design of this MPJ, the theoretical consideration of microwave ignition, the optimization of the nozzle and the simulation results, including the distributions of the electric field inside the TE103 rectangular cavity as well as the tip of the nozzle. The results show that when the nozzle length passed through the hole on the cavity wall is 1 mm and the power is 500 W, the electric field strength at the position of tip nozzle is above 1.2 x 106 V·m-1 which is higher than the breakdown field strength of the working gases. Both simulation result and the observations of the MPJ are in good agreement. (authors)
