Spatial Distribution of Parameters in Normal Micro-DC Glow Discharge in Air

Design of devices based on glow microdischarges requires a detailed knowledge of spatial distribution of the main plasma parameters, which is almost impossible to obtain experimentally because of the small size of such discharges. This paper presents the results of simulation for flat microdischarge in air using an extended hydrodynamic model. Images of cathode spots for different discharge currents are presented, as well as current-voltage characteristics.
