On Inverse Scattering by Screens

Alves, Carlos J. S.; Ha Duong, Tuong

Inverse Problems, 13(5) (1997), 1161-1176

A generalization of Isakov's theorem to admissible shapes that include screens with a Robin boundary condition (in which the impedance is also an unknown) is presented. We also establish a characterization that enables us to distinguish the far field of plane screens from others. Numerical results using a quasi-Newton method are presented.
