Abstract:
Experiments on the dynamics of scroll waves with initially straight filaments have been carried out in an optical tomography setup using the Belousov-Zhabotinsky reaction. Isoconcentration surfaces and scroll wave filaments were reconstructed. Using a meandering recipe, two instabilities have been observed: the three dimensional meandering instability and the negative line tension instability. The first leads to a flat, zig-zag shaped filament of almost constant length. The second occurred in the long time limit, i.e., at low excitability. Here the filament presents a substantial expansion, and the scroll wave assumes a snaking geometry. Numerical simulations that take into account the decrease in excitability of the reaction medium due to aging corroborate the experimental findings and their interpretation.
