Numerical simulation of a nonequilibrium high-frequency discharge in a converging cylindrical wave

A model of nonequilibrium freely localized (not bounded by the walls of the chamber) discharge in the field of a converging axisymmetric wave is investigated. Evolution of the system in time is studied under conditions where the built-up discharge plasma exerts strong influence on the wave field. It is shown that simple and complex (with several maxima) effectively localized dissipative structures in the distribution of electron concentration can emerge in the system at the developed stage.
