Experimental Validation of Percolation-Based Models for Propagation Prediction

In this letter, an experimental validation of percolation-based approaches for the prediction of wave propagation in random media is presented. Measurements are collected in a real controlled environment, where the obstacles are stochastically placed in a two-dimensional grid according to a known nonuniform density distribution. The obtained results show that, in spite of their simplicity, percolation-based approaches can be applied in real propagation problems.
