A Conditioned Probabilistic Method for the Solution of the Inverse Acoustic Scattering Problem
Mathematics, 2022 In the present work, a novel stochastic method has been developed and investigated in order to face the time-reduced inverse scattering problem, governed by the Helmholtz equation, outside connected or disconnected obstacles supporting boundary ...

A second degree Newton method for an inverse scattering problem for a dielectric cylinder
Hittite Journal of Science and Engineering, 2015 The inverse obstacle scattering problem we are interested is to reconstruct the image of an infinitely long homogeneous dielectric cylinder from the far field pattern for scattering of a time-harmonic E-polarized electromagnetic plane wave. We extend the

Mixed spectral AKNS hierarchy from linear isospectral problem and its exact solutions
Open Physics, 2015 In this paper, the AKNS isospectral problem and its corresponding time evolution are generalized by embedding three coefficient functions. Starting from the generalizedAKNS isospectral problem, a mixed spectralAKNS hierarchy with variable coefficients is

Two dimensional inverse scattering from buried magnetic anomalies
Annals of Geophysics, 2008 This paper deals with the problem of the electromagnetic linear inverse scattering from magnetic anomalies buried in a lossy half space, for a scalar and two dimensional case. First, the formulation of the exact model of the electromagnetic scattering is
