Paper Abstract

The images of square pattern, square superlattice pattern, and hexagonal pattern observed in dielectric barrier discharge are processed to get the exactitude binary images for further investigation. By using spatial correlation function, it is found that both of square and hexagonal patterns show perfect structures, and the square superlattice pattern exhibits an interleaving of two perfect squares with the same wavelength including large and small spots respectively. Furthermore, angular spectral distribution is used to study pattern development. It shows that, square and hexagonal patterns are formed with single modes respectively, while square superlattice pattern is governed by a three wave resonance.
