Surface streamer microwave discharge

Technical Physics, 2002
An atmospheric-pressure pulsed microwave discharge on the surface of an insulating plate and between two insulating fllms is considered. The discharge is initiated in a quasi-optical microwave beam away from the beam-forming elements. The TEM field of the beam is less than the critical breakdown value.

Enhancement of surface discharge in catalyst pores in dielectric barrier discharges

Journal of Applied Physics, 2019
The generation of high-density plasmas on the surface of porous catalysts is very important for plasma catalysis, as it determines the active surface of the catalyst that is available for the reaction.

Dimethyl phthalate elimination from micro-polluted source water by surface discharge plasma: Performance, active species roles and mechanisms.

Journal of Hazardous Materials, 2018
Plasticizer pollution brought huge risks to ecological environment and human health. Surface discharge plasma (SDP) was employed to eliminate plasticizer in natural water, with dimethyl phthalate (DMP) as a typical plasticizer.

Mechanisms of charge-induced surface discharge under positive impulse voltages

Journal of Physics D: Applied Physics
Charge-induced surface flashover is a critical factor leading to insulation failures in high-voltage direct current gas-insulated equipment, and the underlying mechanisms are still unclear.

The role of time-lag in the surface discharge inception under positive repetitive pulse voltage

Physics of Plasmas, 2018
Polyetheretherketone is used in the packaging of high voltage power electronics as a frame material, and the surface discharge behaviors of polyetheretherketone are the main concerns for the packaging design. Pulse width modulation voltage, which shows a

Pulse-periodic surface discharge

Soviet Journal of Quantum Electronics, 1983
An investigation was made of a pulse-periodic surface (gliding) discharge of the kind used in electric-discharge excimer lasers. In contrast to a bulk discharge, the surface discharge remained homogeneous at high pulse repetition frequencies without the need to replace the gas in the discharge zone.

Surface discharges on polymeric insulator shed surfaces

IEEE Transactions on Dielectrics and Electrical Insulation, 1997
This paper describes results of an experimental investigation into surface discharges occurring on the surface of polymeric insulators. Discharges on partially hydrophobic surfaces were found to occur across well defined dry bands, while discharges on hydrophobic surfaces appeared as small points of light occurring between discrete water drops.
