Numerical and experimental assessment of a phase retrieval technique applied to planar near field distribution for wide band application

Résumé : The work presented in the following is devoted to the characterization of an harmonic source in a wide band of frequencies [0.5, 20 GHz] from the knowledge of the amplitude-only electric fields at near field measurement distance. Such a problem leads to the development of a “phase reconstruction” algorithm. In that paper a classical propagation/retro-propagation scheme has been applied. This is the first step of a study concerning the characterization of electromagnetic pulsed source from phaseless measurement techniques in near field conditions. The algorithm has been tested and validated using numerical and experimental data acquired at different frequencies and in different configurations.
