Photonic-dispersion neural networks for inverse scattering problems [PDF]

open access: yesLight: Science & Applications, 2021
Inferring the properties of a scattering objective by analyzing the optical far-field responses within the framework of inverse problems is of great practical significance.

Uncertainty Quantification in Inverse Scattering Problems [PDF]

open access: yesEntropy
Inverse scattering problems seek anomalies in a medium given data measured after the interaction with emitted waves. Due to noise, predictions about the nature of these inclusions should be complemented with uncertainty estimates. To this end, we propose

Improved TV-CS Approaches for Inverse Scattering Problem [PDF]

open access: yesThe Scientific World Journal, 2015
Total Variation and Compressive Sensing (TV-CS) techniques represent a very attractive approach to inverse scattering problems. In fact, if the unknown is piecewise constant and so has a sparse gradient, TV-CS approaches allow us to achieve optimal ...

Through-the-Wall Microwave Imaging: Forward and Inverse Scattering Modeling [PDF]

open access: yesSensors, 2020
The imaging of dielectric targets hidden behind a wall is addressed in this paper. An analytical solver for a fast and accurate computation of the forward scattered field by the targets is proposed, which takes into account all the interactions of the ...

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 ...

Electromagnetic Inverse Scattering of Rotating Axisymmetric Objects

open access: yesIEEE Access, 2021
The electromagnetic inverse scattering problem for rotating axisymmetric objects is studied. A modification of a previously proposed two-step algorithm is adopted to obtain the first solutions to the problems of interest.
