| Abstract
| - Pattern formation is investigated in a modified ferroin-catalyzed Belousov−Zhabotinsky (BZ) reaction underthe conditions where the stirred system exhibits sequential oscillations. In accord with the temporal dynamics,sequential waves which are separated by a long quiescent time during which the system does not support anywave activity are achieved, providing the first experimental evidence of the connection between revival waveformation and dynamics of sequential oscillations. The initial wave and quiescent window, which last forseveral hours, are characterized as a function of 1,4-cyclohexanedione, sulfuric acid, and bromate concentrations.In addition to the strong photosensitivity, where both the initial and revival waves can be quickly quenchedby illumination, this modified BZ medium also exhibits the potential of producing complex spatiotemporalbehavior such as waves with anomalous dispersions.
