Plasma Jet-to-Jet Coupling Behavior Between Two Plasma Jet Arrays for Surface Treatments Requiring Strong Discharge Process

The plasma jet-to-jet coupling behavior between two plasma jet arrays is investigated. A plasma array structure consisting of two plasma jet arrays and a double electrode configuration is used as an ambient plasma source and shown to generate a strong plasma emission. Since the proposed plasma device is able to generate an intense plasma emission without any external ground electrode, it is a promising tool for surface treatments and modifications that require a strong discharge process, regardless of the dielectric property of the target material.
