Robust shape reconstruction of elastic impenetrable scatterers via monotonicity spectral sampling methods
Mengjiao Bai, Huaian Diao, Weisheng Zhou
Reconstructing the location and shape of an unknown impenetrable scatterer from far-field measurements is a fundamental inverse problem in elastic scattering. In this paper, we pro…
