Wave pattern dynamics in fluctuating media Sagués Mestres, Francesc Alonso Muñoz, Sergio Sancho Herrero, José María Universitat Politècnica de Catalunya.

Our study focuses on a simple model for excitable systems. Regular waves are created and sustained out of noise when the system is forced with random perturbations. Explicit results for the generation and dynamics of rings and targets are presented. Peer Reviewed Postprint (published version) 2002-11-01 Article Sagués, F.; Alonso, S.; Sancho, J.M.
