SIAM Journal on Imaging Sciences, 2022, 15 (3), pp.1576-1600. ⟨10.1137/21M1457783⟩
International audience; We propose a rapid and robust iterative algorithm to solve inverse acoustic scattering problems formulated as a PDE constrained shape optimization problem. We use a level-set method to represent the obstacle geometry and propo

Publikováno v: Inverse Problems
Inverse Problems, 2023, 39 (5), pp.055001. ⟨10.1088/1361-6420/acc19a⟩
We revisit the differential sampling method introduced in (Haddar and Nguyen 2017 Comput. Math. Appl. 74 2831–55) for the identification of a periodic domain and some local perturbation. We provide a theoretical justification of the method that avo

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, Royal Society, The, 2020, 476 (2244), pp.20200612. ⟨10.1098/rspa.2020.0612⟩
In this paper, we develop a conceptually unified approach for characterizing and determining scattering poles and interior eigenvalues for a given scattering problem. Our approach explores a duality stemming from interchanging the roles of incident a
