Summary:
This paper presents a novel approach to the electromagnetic scattering from apodized surface-relief gratings. The formulation is based on C-method with the help of PPFT. The near field analysis requires a numerical integration with respect to the transform parameter, and the sample points are determined by considering the Wood-Rayleigh anomalies. Numerical experiments of an apodized sinusoidal grating made of conducting material show reliable results and the present formulation seems to be no problem.
