摘要：

The paper considers several examples of non-Debye dielectric response in complex heterogeneous media. The percolation phenomenon and Cole-Cole relaxation in disordered matter are discussed in detail. The proposed models are illustrated by different sample systems: ionic microemulsions, porous glasses, porous silicon, polymer-water mixtures, and polymer-microcomposite materials. The models enable us to establish the relationship between the parameters of dielectric relaxation broadening, structural properties of the media and transport features of charge carriers in the considered systems. In addition, the origins of "strange kinetic" phenomena were discussed based on statistical physics and fractional time evolution ideas. (C) 2002 Elsevier Science B.V. All rights reserved.
