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…
