Layer stripping approach to reconstruct shape defects in waveguides using locally resonant frequencies
Angèle Niclas, Laurent Seppecher
This article present a new method to reconstruct slowly varying width defects in 2D waveguides using one-side section measurements at locally resonant frequencies. At these frequen…
Small defects reconstruction in waveguides from multifrequency one-side scattering data
Eric Bonnetier, Angèle Niclas, Laurent Seppecher +1
Localization and reconstruction of small defects in acoustic or electromagnetic waveguides is of crucial interest in nondestructive evaluation of structures. The aim of this work i…
Stability for finite element discretization of some elliptic inverse parameter problems from internal data -- application to elastography
Elie Bretin, Pierre Millien, Laurent Seppecher
In this article, we provide stability estimates for the finite element discretization of a class of inverse parameter problems of the form $-\nabla\cdot(μS) = \g f$ in a domain …
