Theoretical Modeling of the Interaction Between Two Complex Space Charge Structures in Low-Temperature Plasma
A theoretical model was developed, able to explain complex phenomena that take place at the interaction between two complex space charge structures in low-temperature discharge plasma, leading to the self-modulation of the discharge current. The model is based on the presumption of non-differentiability of both the physical variables and the dynamics equations, which impose their dependence on the scale resolution. The dynamics of the electrons is described by a forced damped oscillating system, being analyzed the response of the global discharge current to different changes in the scale resolution, forcing frequency and damping coefficient. Experimental results were presented, which are in good agreement with the results provided by the theoretical model.
