Dispersion and Absorption in Media with Stretch Exponential and Fractional Power Relaxation
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.
