Abstract :
The general term of the perturbation series is presented in closed form to treat scattering of horizontally polarized plane incident waves from a perfectly conducting rough surface. The use of the complete perturbation series obtained is illustrated through several examples of deterministic profiles, including the case of gently undulating surfaces (Kirchhoff limit) and the case of periodic gratings. Also, it is shown how specularity of the mean scattered field from statistically homogeneous surfaces can be proved in the present context
