In this paper, we consider artificial neural networks for inverse scattering problems. As a
working model, we consider the inverse problem of recovering a scattering object from the …

The fields of photonics and phononics encompass the fundamental science of light and
sound propagation and interactions in complex structures, as well as its technological …

Localized surface plasmons are charge density oscillations confined to metallic
nanoparticles. Excitation of localized surface plasmons by an electromagnetic field at an …

The topological derivative method is recognized as a robust numerical technique in
engineering applications such as topology optimization, inverse problems, imaging …

The multiview total focusing method (TFM) is an imaging algorithm for ultrasonic full matrix
array data that exploits internal reflections and mode conversions in the inspected object to …

In this paper we use the full Maxwell equations for light propagation in order to analyze
plasmonic resonances for nanoparticles. We mathematically define the notion of plasmonic …

An iterative/recursive algorithm is studied for recovering unknown sources of acoustic field
with multifrequency measurement data. Under additional regularity assumptions on source …

We present in this paper a novel numerical reconstruction method for solving a three-
dimensional inverse scattering problem with scattering data generated by a single direction …

Multi-frequency subspace migration imaging techniques are usually adopted for the non-
iterative imaging of unknown electromagnetic targets, such as cracks in concrete walls or …

A rigorous mathematical theory is developed to explain the super-resolution phenomenon
observed in the experiment (Lemoult et al., Phys Rev Lett 107: 064301, 2011). A key …
