摘要:We will discuss an inverse scattering problem of a time-harmonic plane wave incident on a perfectly reflecting random periodic structure. For the forward scattering problem, a stability result is shown. For the inverse problem, we propose an efficient numerical method, which is based on a novel combination of the Monte Carlo technique for sampling the probability space, a continuation method with respect to the wavenumber, and the KL expansion of the random structure. Numerical results are presented to demonstrate the reliability and efficiency of the proposed method.
