Reconstruction of an Impenetrable Obstacle in Anisotropic Inhomogeneous Background (with Jenn-Nan Wang)
Pu-Zhao Kow (National Taiwan University)

Abstract:

In this talk, we consider the problem of determining the shape of obstacles in the acoustic wave scattering with an anisotropic inhomogeneous medium. Precisely, we can reconstruct the obstacle by the eigenvalues and eigenfunctions of the far-field operator. We also provide some numerical simulations.
