Geometry reconstruction from amplitude-only scattered field data

The following contribution presents a profile reconstruction method using amplitude-only information. The idea is to combine a phase retrieval algorithm together with an equivalent currents-based profile reconstruction method. The proposed method is initially conceived to work with planar NF acquisition setups, presenting an application example based on simulated data.
