报告摘要：

In this talk, we will present a framework for the proof of a priori bounds explicitly with respect to frequencies for random surface scattering problems. Besides,an efficient reconstruction method (MCCUQ) is proposed for solving the inverse scattering problem by a random periodic structure, which reconstructs all key statistics of the profile for the unknown random periodic structure from boundary measurements of the scattered fields away from the structure. Numerical results will be presented to demonstrate the reliability and efficiency of the proposed method. The talk is based on a joint work with Gang Bao and Xiang Xu.
