| Summary: | This work aims at investigating the dynamics of spiral waves under the modulation of noise pulses. Both rigid rotating and meandering spirals are considered. The numerical simulations show that for meandering spirals there exists a minimal external radius of the tip trajectory at an optimal intensity when keeping the duration constant, or for an optimal duration when keeping the intensity constant. For rigid rotating spirals an interesting phenomenon is that the clockwise-counterclockwise transition of the trajectory occurs when we raise the duration of the noise pulse for a fixed intensity. |
