Analysis of the effects of complex electrode geometries on the energy deposition and temporally and spatially averaged electric field measurements of surface dielectric barrier discharges

Abstract

Surface dielectric barrier discharges (SDBDs) have been gaining interest in part due to their scalability and flexibility of materials used, allowing larger electrodes with more complex geometries. This paper seeks to elucidate the properties of SDBD geometries utilizing differing repeated lattice structures. Voltage and current traces, optical emission spectroscopy, digital imaging, and numerical analysis are used to analyze the electrodes. Temporally and spatially averaged reduced electric fields and the total power deposited into the plasma are presented. The averaged reduced electric field is not significantly affected by increasing applied voltage, but minor variations could be observed due to the geometry of the electrode lattice structures. Finally, plasma power does not track linearly with perimeter in these more complicated lattice structures.

Plasma Control: A Review of Developments and Applications of Plasma Medicine Control Mechanisms

“…The breakdown voltage needed for the ignition of the plasma is dependent on several factors including chamber, geometry, medium, pressure, and temperature. Voltage control can be manually tailored through the electrode geometry in its thickness, size, and shape, due to electric field enhancements [63]. Voltage control in plasmas can also be achieved through the adjustment of the supply voltage in a power supply.…”
