報告題目:  Uniqueness and numerical methods for imaging an inhomogeneous cavity

報告內容:  In this talk I will introduce the inverse problem of scattering of time-harmonic acoustic waves by inhomogeneous cavities. Some uniqueness results will be provided for the determination of the interior interface by measurements corresponding to many incident point sources. Then the factorization method is proved to be valid in reconstructing the interior interface by using the same measurements. Finally, we carry out several numerical examples to illustrate the practicability of the inversion algorithm.
