Inverse Scattering Problem for the Maxwell’s Equations [PDF]

open access: yesMathematical Modelling of Natural Phenomena, 2013
Inverse scattering problem is discussed for the Maxwell's equations. A reduction of the Maxwell's system to a new Fredholm second-kind integral equation with a {\it scalar weakly singular kernel} is given for electromagnetic (EM) wave scattering. This equation allows one to derive a formula for the scattering amplitude in which only a scalar function ...

Solutions associated with discrete and continuous spectrums in the inverse scattering method for the Vakhnenko-Parkes equation [PDF]

open access: yes, 2012
In this paper the inverse scattering method is applied to the Vakhnenko-Parkes equation. We describe a procedure for using the inverse scattering transform to find the solutions that are associated with both the bound state spectrum and continuous ...

On the quantum inverse scattering problem [PDF]

open access: yesNuclear Physics B, 2000
A general method for solving the so-called quantum inverse scattering problem (namely the reconstruction of local quantum (field) operators in term of the quantum monodromy matrix satisfying a Yang-Baxter quadratic algebra governed by an R-matrix) for a large class of lattice quantum integrable models is given.

A note on an inverse scattering problem [PDF]

open access: yesProceedings of the American Mathematical Society, 1979
Here it is shown that the inverse scattering problem of a plane wave incident off a spherically symmetric medium is an improperly posed problem and that if a continuous index of refraction exists, then it is unique.

The method of fundamental solutions for Helmholtz-type problems [PDF]

open access: yes, 2013
The purpose of this thesis is to extend the range of application of the method fundamental solutions (MFS) to solve direct and inverse geometric problems associated with two- or three-dimensional Helmholtz-type equations.

A Conditioned Probabilistic Method for the Solution of the Inverse Acoustic Scattering Problem

open access: yesMathematics, 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 ...

Low-Coherence Interferometric Imaging: Solution of the One-Dimensional Inverse Scattering Problem [PDF]

open access: yes, 2004
Optical coherence tomography (OCT) is a non-invasive imaging technique based on the use of light sources exhibiting a low degree of coherence. Low coherence interferometric microscopes have been successful in producing internal images of thin pieces of ...
