Formulas for phase recovering from phaseless scattering data at fixed frequency (1502.02282v2)
Published 8 Feb 2015 in math-ph and math.MP
Abstract: We consider quantum and acoustic wave propagation at fixed frequency for compactly supported scatterers in dimension $d\ge 2$. In these framework we give explicit formulas for phase recovering from appropriate phaseless scattering data. As a corollary, we give global uniqueness results for quantum and acoustic inverse scattering at fixed frequency without phase information.
