We report observation of self-organized multilayer plasma patterns formed along the length of an atmospheric pressure glow discharge generated over a wide frequency range from 10-100 kHz. Index Terms--Atmospheric pressure glow discharges, double layers, sell-organization, striation.

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 self-organized plasma patterns are stable and their presence remains even when individual atmospheric glow plasmas couple with one another. Index Terms--Atmospheric pressure glow discharges, plasma coupling, self organization, striation.
