A resonator-based dual-frequency driven atmospheric pressure plasma jet

Abstract An atmospheric-pressure argon plasma jet featuring a novel integrated resonator-based multi-frequency impedance matching is presented and briefly characterized. Two narrow RF frequency bands can be chosen for operation or used simultaneously. This includes mode with the higher value being exactly five times lower one. Phase-resolved optical emission spectroscopy measurements show distinct influence of input combination on discharge dynamics. Measurements dissipated electrical power spectrum each operating complete basic characterization device. Although it constructively much simpler more compact than dual-frequency discharges using conventional system, device shows an excellent performance in operation.
