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.
