Cole-Cole equation

Cole-Cole equation

The Cole-Cole equation is a dielectric relaxation model that constitutes a special case of Havriliak-Negami relaxation when the symmetry parameter (β) is equal to 1 - that is, when the relaxation peaks are symmetric:

hat{varepsilon}(omega) = varepsilon_{infty} + frac{Deltavarepsilon}{1+(iomega au)^{alpha

Most polymers show dielectric relaxation patterns that can be accurately modeled by this equation.
