Dependences of the conductivity σ (a) and dielectric constant ε′ (b) on frequency at various concentrations of GNP: 1, 1 wt%; 2, 5 wt%; 3, 10 wt%; 4, 15 wt%; 5, 20 wt%. For disordered three-dimensional media, which include polymer composites with conducting fillers, the frequency dependence of conductivity usually follows
