Spectrum Comparative Analysis of the Frequency Domain Complex Cole-Cole Mode

Article Preview

Abstract:

Using MATLAB the spectrum comparative analysis was gived between complex Cole-Cole model and basic Cole-Cole model when theirs parameters change. The results show that the complex resistivity curve shape of complex model is limitted by total variation of two same kind parameters of complex model. The variation rule of the curve shape is consistent with basic mode when same kind parameters change. The influent of polarization rate and frequency correlation coefficient is bigger than time constant parameter. The resistivity curve of parallel complex model and series complex model is very similar. Then points out the difficulties and problems faced by the extraction of IP parameters.
