报告摘要：This talk is concerned with the inverse scattering problem of recovering an inhomogenous penetrable obstacle with a conductive boundary condition. The well-posedness of the scattering problem is first established in Lp spaces, and the singularity of solutions is then illustrated in detail by using the integral equation method. Finally, some new uniquenees results are shown i.e., the inhomogenous obstacle can be uniquely recovered by the acoustic far-field pattern at one fixed frequencys and some physical coefficients can be partially determined by the same mearsuremens.
