Abstract
The present contribution deals with ray propagation in semi‐infinite percolation lattices consisting of a succession of uniform density layers. The problem of analytically evaluating the probability that a single ray penetrates up to a prescribed level before being reflected back into the above empty half‐plane is addressed. A hybrid approach, exploiting the complementarity of two mathematical models in dealing with uniform configurations, is presented and assessed through numerical ray‐tracing‐based experiments to show improvements upon previous predictions techniques. © 2007 Wiley Periodicals, Inc.
