Abstract
In this work the global behavior of a parallel array of Josephson junctions is investigated. The single junction, driven by a periodic forcing, behaves chaotically, and is locally coupled in an array of 128 junctions, closed on a parallel resistive load. The array exhibits spatio-temporal chaos. When a spatial diversity is applied, self-organization and pattern formation arise. Moreover, when the spatial diversity is generated by a chaotic law, the attitude of the system to synchronization increases.
