Double-threshold percolation behavior of effective kinetic coefficients.
We investigate thresholds of percolation in two-phase macroscopically inhomogeneous media. It is shown that, unlike standard percolation behavior there are systems in which effective kinetic coefficients of two-phase macroscopically inhomogeneous media have two percolation thresholds. As examples, thermoelectric and galvanomagnetic phenomena in such media are considered.
