Direct and Inverse scattering in a three-dimensional planar waveguide
Yan Chang, Yukun Guo, Yue Zhao
In this paper, we study the direct and inverse scattering of the Schrödinger equation in a three-dimensional planar waveguide. For the direct problem, we derive a resonance-free re…

Jointly determining the point sources and obstacle from Cauchy data
Deyue Zhang, Yan Chang, Yukun Guo
A numerical method is developed for recovering both the source locations and the obstacle from the scattered Cauchy data of the time-harmonic acoustic field. First of all, the inci…
