We treat the stability of determining the boundary impedance of an obstacle by scattering data, with a single incident eld. A previous result by Sincich (SIAM J. Math. Anal. 38, (2006), 434-451) showed a log stability when the boundary of the obstacle is assumed to be C1;1-smooth. We prove that, when the obstacle boundary is merely Lipschitz, a log-log type stability still holds.

Abstract

We treat the stability of determining the boundary impedance of an obstacle by scattering data, with a single incident eld. A previous result by Sincich (SIAM J. Math. Anal. 38, (2006), 434-451) showed a log stability when the boundary of the obstacle is assumed to be C1;1-smooth. We prove that, when the obstacle boundary is merely Lipschitz, a log-log type stability still holds.
