High-frequency instability of wave fronts.
Experimental evidence is presented that a lateral instability of a wave front, as described earlier in a chemically active medium with the Belousov-Zhabotinsky reaction with decreased excitability, can also occur in a medium with any degree of excitability provided that a high-frequency wave train travels through the medium. The interaction of chemical waves with the boundary of the medium can result in the appearance of wave breaks and spiral waves.
