| Abstract | In this paper, we give a positive answer to a longstanding open problem for determining the shape of an obstacle from the knowledge of the far field pattern for the scattering of time-harmonic elastic wave. We show that the elastic far field pattern by an incoming plane wave with a fixed frequency, a fixed incident direction and a fixed polarization determines the obstacle D and the boundary condition on ∂D uniquely. The boundary condition on ∂D is either the Dirichlet, or the Neumann, or the Robin one. |
