Abstract : In this work, we investigate the inversion of a series of parameters in the context of a 2D elasto-acoustic scattering problem. The inverse problem is solved by using a Newton-like method, where the shape of the scatterer, it is assumed to be Lipschitz-continuous. Herein, we want to recover the shape and material parameters in the case of isotropic and anisotropic materials.
