Abstract :
We show that the empirical Cole-Cole model used to inter-pret low-frequency complex resistivity data does have a physical basis. Such a configuration is a homogeneous conductor loaded by a sparse distribution of spheroidal metallic particles with a polarisable surface layer which can be characterised by an interface impedance.
