报告题目：Simultaneously reconstructing a mixed scatterer with a modified factorization method

报告摘要：In this talk I will introduce the inverse problem of scattering of time-harmonic acoustic waves by a mixed-type scatterer, which is the union of an inhomogeneous penetrable medium with a conductive transmission condition and an impenetrable obstacle with the impedance boundary condition. We aim to develop a modified factorization method to show that both the support of the inhomogeneous medium and the shape and location of the impenetrable obstacle can be simultaneously reconstructed by means of the far-field data. Numerical examples are presented to illustrate the feasibility and effectiveness of the proposed inversion algorithms.
