Abstract :
This work presents an innovative two-step methodology for the electromagnetic imaging from amplitude-only measurements of the total field. At the first stage, an inverse source algorithm is used to estimate the distribution of the incident field inside the investigation area. Successively, the unknown profile is directly retrieved from phaseless data by means of an iterative multiresolution procedure integrated with a particle swarm optimizer
