Scattering from a lossy sinusoidal surface is examined by using two methods: extended boundary condition (EBC) and perturbation. The range of applicability of the perturbation approach is established by comparison with EBC. The range of applicability of EBC is established through numerical examples. A convergence criterion based on the sequence of partial sums of the scattered energy is suggested for the application of EBC to lossy surfaces. New analytical expressions for the perturbation solutions are given.
