In a very large frequency mismatch searching region, we observe three different pattern formation phenomena: (a) phase-synchronization-induced invasion under a relatively small frequency mismatch, i.e., the spiral wave with slower frequency (longer period) is swept away by a traveling wave, which is induced and phase synchronized by the faster spiral wave; (b) the coexistence of two spiral waves at sufficiently large parameter mismatch; and (c) an intermediate state, a non-phase-synchronous invasion, that is, similarly the slower spiral wave is swept by an approximate planar wave, whose frequency, however, is intermediate between those of the faster and slower waves. A point-source model is studied to analyze all these phenomena in a unified way. ©2005 The American Physical Society. | Source Title: | Physical Review E - Statistical, Nonlinear, and Soft Matter Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/53089 | ISSN: | 15393755 | DOI: | 10.1103/PhysRevE.71.036212 |
