報告摘要:In this talk, I will report our recent developments on scattering and inverse scattering by locally rough surfaces. A novel technique is introduced to prove the well-posedness of the scattering problem in $L^p$ spaces. Based on this technique, a global uniqueness theorem was proved and several numerical methods were proposed for the inverse problem by means of the fixed frequency scattered data.
