Imaging inhomogeneous targets from intensity only measures of their diffracted fields

The aim of this communication is to show preliminary results achieved by processing experimental data provided by the Institute Fresnel of Marseille for imaging inhomogeneous targets from intensity only measures of their diffracted fields. The proposed procedures and the reported theoretical considerations, inspired by previous works published by the authors, allows to state that also in this more difficult case, it is possible to achieve accurate permittivity and conductivity reconstructions of the unknown targets. The use of multi-frequency data is mandatory to this aim.
