The dielectric spectroscopy (DS) method occupies a special place among the numerous modern methods used for physical and chemical analysis of material, because it enables investigation of dielectric relaxation processes in an extremely wide range of characteristic times (10⁶ - 10^-12 s). Intermolecular interactions and cooperative processes may be monitored by help of DS, which provides a link between the properties of the individual constituents of a complex material to the characterization of its bulk properties. The successful development of the time domain dielectric spectroscopy method (generally called time domain spectroscopy - TDS) and Broadband Dielectric Spectroscopy (BDS) have radically changed the attitude towards DS, making it an effective tool for investigation of solids and liquids, on the macroscopic, mesoscopic and microscopic levels.
