Abstract: In this paper, we propose the Phaseless Data Subspace-based Optimization Method (PDSOM) in the framework of the Method of Moments(MoM) so as to reconstruct the relative-permittivity profiles of extended scatterers in Transverse Electric case, by utilizing only phaseless measurements (i.e., intensity data of the total field with no phase information). The numerical result demonstrates that the proposed method is capable of reconstructing complicated patterns with rapid rate of convergence and robust immunity to noise; and, more importantly, the com- parison unravels the framework-dependence of PDSOM, i.e., PDSOM in the framework of MoM outperforms PDSOM in framework of coupled dipole method (CDM), which supplies a new way of improving the capability of reconstruction.
