The appropriate description of light scattering (transmission/re
ection) at a bulky
artificial medium, consisting of a sequence of functional metamaterial and natural material films,
represents a major challenge in current theoretical nanooptics. Because in many relevant cases,
in particular in the optical domain, a metamaterial must not be described by an effective permittivity
and permeability the usual Fresnel formalism cannot be applied. A reliable alternative
consists in using a Bloch mode formalism known e.g. from the theory of photonic crystals. In
this contribution we present the theoretical background and apply the formalism to the quite
general problems of re
ection/transmission at a metamaterial film sandwiched either between a
homogeneous or a dissimilar metamaterial.
