%X This paper focuses on the dielectric reconstruction from amplitude-only data by means of the Iterative Multi-Scaling Strategy. Such a methodology is considered to fully exploit the reduced information content achievable from phaseless measurements allowing a satisfactory spatial resolution in the investigation domain. In order to preliminary evaluate the performance of the proposed approach, a representative test case is analyzed and the results are compared with those of the full-data approach. %D 2011 %A Massimo Donelli %A Garbiele Franceschini %A Davide Franceschini %A Andrea Massa %I University of Trento %L elediasc12368 %T On the Effects of Phase Information on the Reconstruction Capabilities of the Iterative Multi-Scaling Strategy
