A modified scheme of sparse‐matrix canonical‐grid (SMCG) method for simulation of rough surface scattering is developed. It employs an interpolating Green's function based on Chebyshev polynomial approximation to replace the Taylor series expansion in the previous SMCG methods, which becomes intractable for high‐order terms. This modified scheme is more efficient and flexible, and suitable for arbitrary roughness. © Wiley Periodicals, Inc.
