The relevance of the article under consideration is due to the fact that it optimizes the conditions for obtaining non-thermal plasma at atmospheric pressure using a dielectric barrier discharge (DBD) in a packet-pulse excitation mode. This type of discharge is widely used in practice as an effective method for modifying various media. It is shown that for a discharge gap of the millimeter range (~3 mm) in atmospheric air, under certain conditions, a number of new plasma phenomena are possible – the effects of an increase in the density (total number) of filamentary discharges over time, both unchanged and with a decrease in the area of the filaments, as well as the formation of new complex space-time structures. An interpretation of this phenomenon is proposed. Homogeneous diffuse discharges are obtained in a standard electrode configuration with a single dielectric.
