Gas discharges in the plasma atmosphere are known to consist of a collection of different particles,
mainly electrons, ions, neutral atoms, and molecules. The present need is to characterize the plasmas and
optimization of the designed plasma system under variable conditions. In this work, a time-dependent, onedimensional
simulation of an optimized DBD device, driven by a sinusoidal alternating high voltage, in argon
gas is demonstrated. First of all, a DBD device with two electrodes, covered by the dielectric and with the
variable discharge gap was assumed, and the discharge parameters were simulated versus time across the
plasma gap. A comparison between the results is carried out. In the second part, with a fixed gap that was
obtained from previous section, when the dielectric thickness changed, the plasma parameters were simulated.
In the third case, with a fixed discharge gap and dielectric thickness, the plate diameters were varied
and the best diameter was selected to deliver th
