Abstract: In order to modelize the propagation of pressure waves in porous media, we study the diffusion of electric charges on two-dimensional model systems. For homogeneous structures, we show that complex impedance measurements agree with theoretical predictions. In the case of percolation lattices, we observe experimentally an “anomalous diffusion” behaviour. We analyse these observations using classical results from the percolation theory.
