Asymptotic analysis of the transmission eigenvalue problem for a Dirichlet obstacle coated by a thin layer of non-absorbing media
Fioralba Cakoni, Nicolas Chaulet, Houssem Haddar
We consider the transmission eigenvalue problem for an impenetrable obstacle with Dirichlet boundary condition surrounded by a thin layer of non-absorbing inhomogeneous material. W…
Analysis of the factorization method for a general class of boundary conditions
Mathieu Chamaillard, Nicolas Chaulet, Houssem Haddar
We analyze the factorization method (introduced by Kirsch in 1998 to solve inverse scattering problems at fixed frequency from the far field operator) for a general class of bounda…
On the asymptotics of a Robin eigenvalue problem
Fioralba Cakoni, Nicolas Chaulet, Houssem Haddar
The considered Robin problem can formally be seen as a small perturbation of a Dirichlet problem. However, due to the sign of the impedance value, its associated eigenvalues conver…
On simultaneous identification of the shape and generalized impedance boundary condition in obstacle scattering
Laurent Bourgeois, Nicolas Chaulet, Houssem Haddar
We consider the inverse obstacle scattering problem of determining both the shape and the "equivalent impedance" from far field measurements at a fixed frequency. In this work, the…
Stable reconstruction of generalized impedance boundary conditions
Laurent Bourgeois, Nicolas Chaulet, Houssem Haddar
We are interested in the identification of a Generalized Impedance Boundary Condition from the far--fields created by one or several incident plane waves at a fixed frequency. We f…
