Dielectric alpha-relaxation modelled by a Havrialiak-Negami function
Cross-over of the dielectric permeability from a low-frequency limit of 60 to a high-frequency limit of 3, modelled by the Havrialiak-Negami function with exponents alpha=0.6, gamma=0.9. For comparison, the dashed lines show Debye relaxation (alpha=gamma=1).
