hierarchical_section_title: Dielectric barrier discharge
caption_attribution_description: English: 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.
context_page_description: Dielectric-barrier discharge is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent discharge and also known as ozone production discharge or partial discharge, it was first reported by Ernst Werner von Siemens in 1857. On right, the schematic diagram shows a typical construction of a DBD 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. Below this, the photograph shows an atmospheric DBD discharge occurring in between two steel electrode plates, each covered with a dielectric sheet. The filaments are columns of conducting plasma, and the foot of each filament is representative of the surface accumulated charge.
