Abstract: This paper is devoted to structured surfaces and their applications to absorption and transmission enhancement. In this paper we study phenomenology of the absorption phenomenon obtained with complex structures. We consider the scattering of an electromagnetic plane wave by a bi-periodic array of gaps in a conducting plane. We show in this paper that this kind of bi-periodic gaps combined with a lossy dielectric material deposited on a metallic plane can become an absorbing structure and very small ordered slits in a conducting plane permit field penetration and transmission enhancement of the incident electromagnetic field.

Keywords: electromagnetic scattering; structured surfaces; bi-periodic gaps; optical absorption; microwave absorption; enhanced transmission; surface waves; electromagnetic plane waves; lossy dielectric material; deposition.
