We apply boundary integrals to the analysis of diffraction from both conductive and dielectric diffractive optical elements. Boundary integral uses form wave equation describe induced surface distributions over a element. The are used determine diffracted fields anywhere in space. In contrast other vector techniques, methods not restricted infinitely periodic structures but extend finite aperiodic as well. element method solve equations validate its implementation by comparing with analytical solutions our results for circular conducting cylinder cylinder. also present plate, linear grating, an eight-level off-axis lens, on-axis binary lens that has subwavelength features.
