I. Introduction
Dielectric barrier discharges (DBDs) offer specific properties that are very interesting for a large number of processes. The obtained plasma is maintained at low temperatures, the barriers contribute to spread the discharge on the whole surface of the electrodes and they avoid direct contact between the metallic electrodes and the gas. Thus, it increases lifetimes and reduces costs. For these reasons, DBD are widely used in industrial applications such as ozone generators, surface treatments, thin film deposits and coating, lighting, and displays [1]–[3].
