Nonorganized deterministic dissymmetries induce regularity in spatiotemporal dynamics

This letter deals with the remarkable effects observed in arrays of circuits and systems when parameter spatial diversity is induced by using chaos, leading to pattern formation and regularization. The communication emphasizes the fact that generating spatial dissymmetries by using chaos enhances regularity and pattern formation capability with respect to the case in which diversity is generated by random processes. Several examples are reported showing the previous conjecture. A further aim of the paper is to emphasize that the introduction of a small amplitude chaotic spatial diversity could control chaos in both 1D and 2D large scale connected arrays of nonlinear circuits like Cellular Neural Network (CNN).
