Abstract
The authors study a model for layered porous media. The model is a d-dimensional lattice percolation system with different concentrations given to different layers. They find for the 2D site percolation system, a critical line on which the percolation clusters are anisotropic and characterized by two different correlation length exponents. Their results suggest that due to the introduction of long-range correlations one obtains a new universality class different from isotropic percolation and from directed percolation.Keywords
