An Inverse Mixed Impedance Scattering Problem in a Chiral Medium

Mathematics, 2021
An inverse scattering problem of time-harmonic chiral electromagnetic waves for a buried partially coated object was studied. The buried object was embedded in a piecewise isotropic homogeneous background chiral material.

Important Issues on Spectral Properties of a Transmission Eigenvalue Problem

International Journal of Differential Equations, 2021
Nowadays, inverse scattering is an important field of interest for many mathematicians who deal with partial differential equations theory, and the research in inverse scattering is in continuous progress. There are many problems related to scattering by

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

Application of Whale Optimization Algorithm to Inverse Scattering of an Imperfect Conductor with Corners

International Journal of Antennas and Propagation, 2020
In this paper, the whale optimization algorithm (WOA) is applied to the inverse scattering of an imperfect conductor with corners. The WOA is a new metaheuristic optimization algorithm. It mimics the hunting behavior of humpback whales.

A novel inverse scattering approach for a stratified slab without explicit knowledge of incident fields [PDF]

, 2012
A novel inverse scattering approach in time domain is presented for reconstructing electrical parameters of a stratified slab. The approach based on the field equivalence principle does not need explicit information of incident fields.

Scattering matrices with finite phase shift and the inverse scattering problem

, 1996
The inverse scattering problem for the Schrodinger operator on the half-axis is studied. It is shown that this problem can be solved for the scattering matrices with arbitrary finite phase shift on the real axis if one admits potentials with long-range ...

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

Using Alternating Minimization and Convexified Carleman Weighted Objective Functional for a Time-Domain Inverse Scattering Problem

Axioms, 2023
This paper considers a 1D time-domain inverse scattering problem for the Helmholtz equation in which penetrable scatterers are to be determined from boundary measurements of the scattering data.
