Research Abstract

We investigated the response of dissipative structures of electroconvections (ECs) to external noise. Due to the intrinsic mechanisms of ECs, noise-induced thresholds and wavelengths were completely different from one another. The response strongly depended on the characteristic of noise (e.g., white or colorednoises). In particular, our results of the wavelength variations (of chevrons in high frequency region) are quite useful for fabricating modulated polymer surfaces by means of ECs.
