“…Surface charges play an important role in the breakdown location of microdischarges [24], and therefore it is necessary to investigate the effect of the travel distance on the broken location of microdischarges. It has been demonstrated that surface charges can move synchronously with a rotating dielectric barrier [43].…”

“…However, the memory effect of surface charges is strongly detrimental to the uniform distribution of filamentary discharges. Microdischarges are preferably ignited at the positions of accumulated surface charges in the foregoing half period because of the local electric field enhancement [24,25]. Bogaczyk et al found that although new microdischarges can occur in some discharge-free regions, the most frequently observed phenomenon is the repeated ignition of microdischarges at the same positions [26].…”

The application performance of the dielectric barrier discharge (DBD) depends on plasma characteristics, especially discharge energy and uniformity. In this study, the plasma characteristics are investigated in a DBD device with a rotating dielectric barrier. The statistical results indicate that rotating a dielectric barrier can effectively improve discharge power and the number of current pulses. Compared to a stationary DBD, the grayscale standard deviation of the discharge images can be significantly reduced, and the microdischarges present a rather diffuse distribution in the rotational DBD. This rotation also leads to an increase in the number of microdischarges and their movement in the direction of rotation. Additionally, a CFD numerical simulation together with the solution of the diffusion and recombination equations for space charges is implemented to study the diffusion, recombination, and transfer with airflow of space residual charges. The results reveal that the space charges move farther than their diffusion limit in most regions when the rotating speed reaches 30 rps (revolution per second). The mechanism of enhancing the discharge energy and uniformity by rotating a dielectric barrier is analyzed based on the local electric field enhancement induced by surface charges and electron detachment from space negative charges.

“…Recently, the Kagome lattice has been presented in and is attracting attention in dielectric barrier discharge (DBD) systems. Dong Lifang et al reported a Kagome lattice with discrete spots clearly visible to the naked eye in a complex hexagonal superlattice pattern [16]. Sun Haoyang et al isolated a Kagome lattice based on the triangular pattern which is invisible to the naked eye [17].…”

“…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.…”

“…In recent years, the DBD system, known for its incredible accessibility and utility for experimental devices, has been verified as an amazing and preferred system for the investigation of pattern dynamics, because it exhibits an exceptionally great variety and abundance of self-organized patterns [16][17][18][19][20][21][22][23]. Due to the luminous intensity, there not only exist visible discharge filaments to the naked eye or an ordinary camera, which is called normal discharge, but also discharge filaments exist that are invisible to the naked eye or an ordinary camera, which called dark discharge in the DBD system.…”

A honeycomb-Kagome hexagonal superlattice pattern with dark discharges is observed in dielectric barrier discharge (DBD) system for the first time. The spatiotemporal structure of the honeycomb-Kagome hexagonal superlattice pattern with dark discharges investigated by an intensified charge-coupled device (ICCD) and the photomultipliers (PMTs) shows that it is an interleaving of three different sub-lattices, which are bright-spot, invisible honeycomb lattice, and Kagome lattice with invisible frameworks and dim-spots, respectively. The invisible honeycomb lattices and Kagome lattices are actually composed of the dark discharges. By using optical emission spectra method, it is found that the plasma parameters of the three different sub-lattices are different. The influence of the dark discharges on the pattern formation is discussed. The results maybe have significance for the investigation of the dark discharges and will accelerate the development of the self-organized pattern dynamics.

We report on the striped superlattice pattern in dielectric barrier discharge for the first time. The spatiotemporal structure of the striped superlattice pattern is investigated by a high-speed framing camera. The result shows that the striped superlattice pattern consists of three different transient sub-lattices which are striped-dots, stripes, and small-dots surrounding a striped-dot, respectively. Images of a single frame indicate that the stripes which look like they are diffused are actually made up of individual filaments. The optical emission spectra of different sub-lattices are collected and investigated; it is found that plasma parameters of the three different transient sub-lattices are different. The formation mechanism of the striped superlattice pattern is discussed. And a tunable plasma photonic crystal with one and two-dimensions structures which has the dynamic controllability based on the striped superlattice pattern is present.
