Solving forward and inverse wave scattering via boundary integral equations and deep learning. Applications to cloaking design
Camille Carvalho, Elsie Cortes, Symeon Papadimitropoulos +1
We propose a deep learning framework based on an encoder-decoder architecture for the design and evaluation of cloaking devices, demonstrated in this work for two-dimensional wave…
Discretization in Multilayered Media with High Contrasts: Is It All About the Boundaries?
Camille Carvalho, Stéphanie Chaillat, Elsie Cortes +1
Wave propagation in multilayered media with high material contrasts poses significant numerical challenges, as large variations in wavenumbers lead to strong reflections and comple…
Imaging with super-resolution in changing random media
Alexander Christie, Matan Leibovich, Miguel Moscoso +3
We develop an imaging algorithm that exploits strong scattering to achieve super-resolution in changing random media. The method processes large and diverse array datasets using sp…
Modeling measurements for quantitative imaging subsurface targets
Arnold Kim, Chrysoula Tsogka
We study ground-penetrating synthetic aperture radar measurements of scattering by targets located below a rough air-soil interface. By considering the inherent space/angle limitat…
Super-resolution in disordered media using neural networks
Alexander Christie, Matan Leibovich, Miguel Moscoso +3
We propose a methodology that exploits large and diverse data sets to accurately estimate the ambient medium's Green's functions in strongly scattering media. Given these estimates…
