Abstract
Recent developments in the experimental methods of dielectric spectroscopy are reviewed, and illustrative examples are presented. Besides time domain and frequency domain methods experiments performed as a function of the temperature are also discussed; especially thermally-stimulated techniques. Besides the dielectric methods, the most important related techniques e.g. mechanical spectroscopy, thermally stimulated creep and recovery, and nuclear magnetic resonance methods, are also reviewed briefly because they are very often combined with dielectric spectroscopy. Some useful macroscopic autocorrelation functions are mentioned and discussed in detail.
