Abstract
The properties of metamaterials made of an increasing number of discrete functional layers are analyzed. Convergence of the effective properties towards their bulk counterparts is observed if the light propagation in the metamaterial is dominated by a single eigenmode. The effective properties of the finite structure will be compared to the properties of the infinite structure for which an effective refractive index can be derived from the dispersion relation. The dispersion relation is furthermore shown to be useful in deriving angle dependent effective material parameters. They are compared to the effective properties obtained from a finite slab by applying a dedicated retrieval procedure.
