Davidson-Cole type dielectric dispersion

Figure 2 For packed samples of crushed ice particles, (a) Temperature dependence of the dielectric relaxation time rand (h) Cole-Cole plots of the sample (after 400 h of annealing at -1 °C, 2-4 mm particle size, 536 kg/m packed density) at -10 °C. The dielectric dispersion is of the Davidson-Cole type (a=0.97, f=0.85).

The results described above indicate two interesting facts many samples consisting of packed ice particles exhibit a dielectric dispersion of the Davidson-Cole type, and ice samples grown from the vapor phase exhibit a shorter relaxation time r and a lower activation energy of rthan ordinary ice samples grown from the liquid phase.
