This work investigates the statistical behavior including the dimensions and electrical
properties of a single microdischarge (MD) generated in a planar atmospheric-pressure air
dielectric barrier discharge reactor using a kHz sinusoidal power source with a gap of 1.4
mm. The MD diameters and surface wave (SW) dimensions are captured by an intensified
charge-coupled device camera with currents and charge transferred being recorded. The
average currents measured in positive and negative half periods (HPs) are 58.9 and 50.5 …
