Multilayer plasma patterns in paralleled and coupled atmospheric glow discharges

We report observations of multilayer plasma patterns in multiple atmospheric glow discharges sustained simultaneously with a single power supply. Depending on operation conditions, these atmospheric glow plasmas either operate in parallel, seemingly independent of one another, or undergo structural...

Description
Summary:We report observations of multilayer plasma patterns in multiple atmospheric glow discharges sustained simultaneously with a single power supply. Depending on operation conditions, these atmospheric glow plasmas either operate in parallel, seemingly independent of one another, or undergo structural coupling. In both scenarios, multilayer structures are observed. These selforganized plasma patterns are stable and their presence remains even when individual atmospheric glow plasmas couple with one another.
