Self-Organized Filaments in Dielectric Barrier Discharge in Air at Atmosphere Pressure

The self-organized filament pattern created by dielectric barrier discharges in air at atmosphere pressure is investigated experimentally. The density and dimension of filament are analysed quantitatively. The experimental results show that the distance of neighbour filaments decreases with the increasing applied voltage or with the decreasing width of the gas gap, Also, the diameter of filament also decreases with the increasing applied voltages or with the decreasing width of gas gap.
