Specific features of the dielectric response of heterogeneous systems with a polar matrix containing electrically active inclusions

Experimental investigation of the concentration dependence of the permittivity in ternary disordered systems

“…1), the curve logε'' = f(X 1 , X 2 ) ascends considerably, certainly because the resistivity of the mixture grows. In the majority of theoretical works (see, for example, [17,18]), the dependence of ε' on resistivity ρ is disregarded. However, in [19], such a dependence is suggested for a paraffin-graphite sys tem and the curve logε' = f(x) is approximated both before and after the percolation threshold.…”
