In this paper we present a nonlinear effective inversion method based on the Pade Via Lanczos process (PVL process). The method finds so-called effective medium parameters of some inhomogeneous object by minimizing an objective and the scattered field produced by a homogeneous one. This minization procedure can be carried out by inspection, since the scattered field produced by homogeneous objects can be computed very efficiently using the PVL process. The constant medium parameters of the homogeneous object for which the objective function is minimum are the effective medium parameters we are looking for. A number of numerical experiments are presented in which we illustrate the performance of the method.
