Plasmas at atmospheric pressure are vulnerable to ionization overheating instability followed by a destructive glow-to-arc transition (GAT) as power density increases. We report the characteristics of steady-state atmospheric pressure microplasmas in nonflowing argon and air driven by up to 40 W of microwave power. These microdischarges are supported by either 1) a quarter-wave microstrip resonator or 2) a microstrip transmission line. Modeling shows that the resonator configuration rejects… CONTINUE READING
