Abstract
A mathematical model based on a single excitation mechanism was used for describing the formation of anisotropic chemical wave patterns in the NO+H2reaction on a Rh(110) surface. The experimentally measured bifurcation diagram was reproduced quantitavely to describe the ranges of the spatial patterns in the reaction. The state-independent anisotropy of surface diffusion site-blocking effects were accounted through coadsorbates for the diffusing species. The formation of travelling fragments, appearance of front geometries in the range of double metastability, parameter dependent anisotropy of reaction in the bistable range and that of target patterns in the excitable range were simulated.
