The virtual boundary layer between an atmospheric discharge plasma and the dielectric barrier electrode was observed in the parallel cell reactor. The boundary layer has properties similar to those of a collisional sheath that has a thickness proportional to the discharge density in the diffusive streamer mode discharge and to the applied voltage in the glow mode discharge. The capacitance can be modified by considering the boundary layer during the discharge-on period, which improves the accuracy of analyzing the dissipated power by using the charge-voltage Lissajous diagram.
