Papers by Keyword: Non-Debye Relaxation

Abstract: Mechanical spectroscopy and relaxation phenomena in solids are briefly discussed from the viewpoint of generalized susceptibility and linear response theory. Comparison of mechanical spectroscopy with other spectroscopic techniques is provided in the endeavour to formulate a multidisciplinary approach to selected relaxation phenomena in solids.

Abstract: Dispersion and absorption in a media with stretch exponential or Kohlrausch–Williams– Watts relaxation are considered. The frequency-dependent dispersion and absorption coefficients, phase and group velocities are obtained and compared to Debye–Mandelshtam– Leontovich expressions.
