Transition to rotating chaotic waves in arrays of coupled Lorenz oscillators

In the present paper we report experimental observations of discrete spatiotemporal structures
in rings of unidirectionally coupled analog Lorenz systems. This is an extension of the results
previously reported in [Sánchez & Matías, 1998], studying now other parameter regimes. These
studies are based on the use of an analog circuit corresponding to Lorenz equations. The more
interesting new result is that a route has been found connecting periodic and chaotic rotating
waves in a new kind of transition involving two symmetry related quasiperiodic attractors that
merge at the transition point.
