Honeycomb superlattice pattern in a dielectric barrier discharge in argon/air

Abstract

We report on a honeycomb superlattice pattern in a dielectric barrier discharge in argon/air for the first time. It consists of hexagon lattice and honeycomb framework and bifurcates from a hexagon pattern as the applied voltage increases. A phase diagram of the pattern as a function of the gas component and gas pressure is presented. The instantaneous images show that the hexagon lattice and honeycomb framework are ignited in turn in each half voltage cycle. The honeycomb framework is composed of filaments ignited randomly. The spatiotemporal dynamics of honeycomb superlattice pattern is discussed by wall charges. V

Nonlinear phenomena in dielectric barrier discharges: pattern, striation and chaos

“…The patterns in various states can self-organize into hexagons, squares, rings and stripes. Mixtures of simple structures of DBD can form some complex patterns like honeycomb, superlattice, etc[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Figures2 and 3show a collection of stable DBD patterns obtained by different research groups.…”

Influence of square wave duty ratio on pattern formation of atmospheric pressure glow discharge

“…在大气压气体放电系统中, 如介质阻 挡放电(Dielectric Barrier Discharge, DBD)和阴极层放 电(Cathode Bounday Lay Discharge, CBLD)中, 也发现 了放电的自组织现象. 利用介质阻挡放电装置, Dong 等人观察到了螺旋斑图 [15] 、四边形斑图 [16] 和蜂窝斑 图 [17] 等. 研究发现DBD中自组织斑图由几套不同时 刻放电的子结构嵌套而成, 介质表面壁电荷的分布对 斑图的形成具有重要影响 [18][19][20] .…”

Formation of honeycomb-Kagome hexagonal superlattice pattern with dark discharges in dielectric barrier discharge

“…In addition, the invisible honeycomb lattice is also presented in this work. It is well known that the honeycomb structure, as a basic structure, has been widely reported in the pattern field [16,[18][19][20][21]. However, the invisible honeycomb lattice has not before been presented in a DBD system.…”
