The modelling was performed for the DBD in an asymmetric arrangement with a 1.5 mm gap, electrode radius of 2 mm and 0.5 mm thick dielectric (alumina, relative permittivity 9) covering grounded electrode, driven by sinusoidal voltage (voltage amplitude of 1.3 kV and frequency of 60 kHz, corresponding to a period of T = 16.67 microseconds).
