In this paper, a new numerical method was developed for a precise electric modeling, of some physical samples. The proposed technique is based on the decomposition of the electric impedance of these samples into a series of elementary electric circuits. A numerical procedure using the Levenberg Marquadt algorithm was developed in order to estimate the order and number of these elementary circuits. A polymer diode, based on polyaniline, and a BST ceramic were chosen to test this method. An electric characterization, at low and high frequencies, was carried using a developed electronic system. The developed electric models are compared those often used in the literature. Interesting results are obtained at the level of the statistical errors and the signification of the different elements of the models.
