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.
