Abstract :
In this paper, 2.45-GHz microwave argon plasma jets at atmospheric gas pressure are generated at the end of quartz tube (with an inner radius of 2 mm). With the applied power of 50 W and the different patterns of exciter, the lengths of plasma jet plume out of the end of quartz tube, about 5, 15, and 25 mm, respectively, are obtained. Moreover, the simulated result suggests that the efficient plasma jet with a symmetric hairpin copper wire is attributed to the enhanced electric field of local surface plasmon polaritons.
