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…

Lamb modes and Born approximation for small shape defects inversion in elastic plates

Eric Bonnetier, Angele Niclas, Laurent Seppecher

The aim of this work is to present theoretical tools to study wave propagation in elastic waveguides and perform multi-frequency scattering inversion to reconstruct small shape def…

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…
