Atmospheric Cold Plasma via Fringe Field Enhanced Corona Discharge on Single Dielectric Barrier for Large-volume Applications

This paper is to design and discuss on homogenous atmospheric cold plasma technique. Instead of using the needle tip with a small radius of curvature, this work utilized the twin tips with the sharp edge that can concentrate electric field around the edge of tips, allowing micro-discharge plasma at low power consumption. Our design structure shows a uniform atmospheric-air cold plasma for large-scale surface treatment applications. Furthermore, the designed large-scale atmospheric cold plasmas also provide a great benefit to environmental utilization.
