The paper presents the experimental results relevant to the external electrical influence on the structure of a thin plasma sheet formed atop a substrate surface by Ar plasma jet that is being generated by a coaxial sinusoidal barrier discharge (BD) in an argon flow. The electrical influence on the target is being created due to connecting of a high-voltage or grounded electrode of the BD to the metal plate on which the dielectric or metallic substrate to be treated is located. Such an approach ensures a synchronism of the interaction of the external auxiliary electric field with the own electric field of the ionization wave (plasma bullet) propagating along the argon plasma jet toward the substrate during each period of the BD alternating voltage. An image of the structure of the plasma sheet on the substrate surface averaged over many periods of sinusoidal voltage was recorded in the experiments.
