In this paper, we develop a high order numerical method for the numericalsolutions of scattering problems with slightly perturbed periodic surfaces intwo dimensional spaces. Based on the regularity property introduced in Part I,the decaying rate of the incident field could be transferred directly to thetotal field for small perturbations. Thus the finite section method could reacha high accuracy rate. With the help of a modification of the truncated problem,the problem is solved by a finite element method. The convergence of the finiteelement method is proved and numerical examples have been carried out to showthe efficiency of the numerical scheme.
