K. Agladze et al., TUNNELING CHEMICAL WAVES, Nuovo cimento della Societa italiana di fisica. D, Condensed matter,atomic, molecular and chemical physics, biophysics, 20(1), 1998, pp. 103-111
The tunneling of chemical waves through the gaps of different geometri
cal shapes was studied using a new experimental model based on the pol
ysulphone membranes with the fixed catalyst. Period doubling of the wa
ve train, formation of the wave breaks on the split in polysulphone me
mbrane, drift of the spiral wave along the widening split were observe
d. The effects were confirmed and studied in details using computer si
mulation.
