The Spatiotemporal Pattern Formed in an Atmospheric-Pressure Radio-Frequency Dielectric-Barrier-Discharge Oxygen Plasma

In this paper, we developed a radio-frequency (RF) dielectric barrier oxygen discharge, which consists of a powered brass electrode covered by fused silica as a dielectric layer and a grounded liquid electrode. The self-organized patterns in the RF dielectric barrier discharge at atmospheric pressure are investigated. With increasing the input power, the plasma patterns transform from the ring to the netlike structure.
