CHAOTIC WAVES AND SPATIOTEMPORAL PATTERNS IN LARGE ARRAYS OF DOUBLY-COUPLED CHUAS CIRCUITS

We investigate complex dynamic phenomena in arrays composed of interac ting chaotic circuits. Such arrays can be thought of as a model of non linear phenomena in spatially cells extended (high-dimensional or infi nite-dimensional) systems and active media with potential applications in signal processing, In this paper, we consider a particular structu re of the network in which there exists double diffusive interactions between the cells. Such a double interaction can be considered as a pa radigm and means for understanding very complex interactions existing in real systems where separate cells can communicate in various ways, We consider two basic cases where separate cells without coupling exhi bit two different types of chaotic behavior. Depending on the connecti on structure, initial conditions imposed in the cells, the array exhib its various kinds of spatially ordered chaotic waves. Patterns of beha vior depending on the excitation of the array and the connection struc ture are studied in this paper. Chua's circuits are taken as standard chaotic cells.
