High-pressure SHF-discharge propagation in subbreakdown fields. Plasma structures production

A 3D-model describing propagation of initiated high-pressure SHF-discharge in a linearly polarized wave beam is developed. Equations for electric field amplitude are solved in a self-consistent way with a system of plasmochemical kinetics equations. In the framework of this model the experimentally observed types of plasma structures were obtained, i.e. a serpentine and a chain. Results of the calculations permit ascertaining conditions for formation of this or that spatial structure, as well as parameters of plasmoids formed. Calculations of the rate of charge propagation toward radiation source are compared with the available experimental data
