Dielectric barrier discharge

Typical construction of a DBD device wherein one of the two electrodes is covered with a dielectric barrier material. The lines between the dielectric and the electrode are representative of the discharge filaments, which are normally visible to the naked eye.
A dielectric barrier discharge produced using mica sheets as dielectric, put on two steel plates as electrode. The discharge is taking place in normal atmospheric air, at about 30 kHz, with a discharge gap of about 4 mm. The foot of the discharge is the charge accumulation on the barrier surface.

Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge[1] or partial discharge,[2] it was first reported by Ernst Werner von Siemens in 1857.[3]
