Examples of non-scattering inhomogeneities
Lucas Chesnel, Houssem Haddar, Hongjie Li +1
We consider the scattering of waves by a penetrable inclusion embedded in some reference medium. We exhibit examples of materials and geometries for which non-scattering frequencie…
On the convergence analysis of one-shot inversion methods
Marcella Bonazzoli, Houssem Haddar, Tuan Anh Vu
When an inverse problem is solved by a gradient-based optimization algorithm, the corresponding forward and adjoint problems, which are introduced to compute the gradient, can be a…
The linear sampling method for data generated by small random scatterers
J. Garnier, H. Haddar, H. Montanelli
We present an extension of the linear sampling method for solving the sound-soft inverse scattering problem in two dimensions with data generated by randomly distributed small scat…
Ultrasonic imaging in highly heterogeneous backgrounds
Fatemeh Pourahmadian, Houssem Haddar
This work formally investigates the differential evolution indicators as a tool for ultrasonic tracking of elastic transformation and fracturing in randomly heterogeneous solids. W…
The linear sampling method for random sources
Josselin Garnier, Houssem Haddar, Hadrien Montanelli
We present an extension of the linear sampling method for solving the sound-soft inverse acoustic scattering problem with randomly distributed point sources. The theoretical justif…
Time- vs. frequency- domain inverse elastic scattering: Theory and experiment
Xiaoli Liu, Jian Song, Fatemeh Pourahmadian +1
This study formally adapts the time-domain linear sampling method (TLSM) for ultrasonic imaging of stationary and evolving fractures in safety-critical components. The TLSM indicat…
