Frequency locking of propagating wave fronts in reaction-diffusion systems

More Information
  • Published Date: November 19, 2005
  • We have observed N∶N-1(N≥2) frequency-locking of propagating wave fronts when the light intensity is increased in a spatially extended system. The experiments were carried out using the light-sensitive form of the Belousov-Zhabotinsky reaction. By constructing a mapping function, the characteristic devil′s staircase can be reproduced when plotting wave period versus light intensity, in agreement with the experimental data.
