  abstract = {{A}n inversion code has been constructed using {M}atlab, to recover {I} {D} parameters of the {C}ole-{C}ole model from spectral induced polarization data. {I}n a spectral induced polarization survey, impedances are recorded at various frequencies. {B}oth induced polarization and electromagnetic coupling effects occur simultaneously over the experimental frequency bandwidth, and these become progressively more dominant when the frequency increases. {W}e used the {CR}1{D}mod code published by {I}ngeman-{N}ielsen and {B}aumgartner [2006]. {T}his code solves for electromagnetic responses, in the presence of complex resistivity effects in a 1 {D} {E}arth. {I}n this paper, a homotopy method has been designed by the authors to overcome the local convergence problem of normal iterative methods. {I}n addition, in order to further condition the inverse problem, we incorporated standard {G}auss-{N}ewton (or quasi-{N}ewton) methods. {G}raphical user interfaces enable straightforward entering of the data and the a priori model, as well as the cable configuration. {T}wo synthetic examples are presented, showing that the spectral parameters can be recovered from multifrequency, complex resistivity data.},
