We demonstrate that the presence of interfaces induces anisotropy in the optical properties of thin inhomogeneous layers. Several mechanisms are discussed that can control the properties of this surface-induced anisotropy. We found that the effective refractive indices for s- and p-polarized fields are different and depend on the thickness of the layer, concentration and optical properties of inclusions in the layer, and the angle of incidence.
► We demonstrate that interfaces induces anisotropy in the optical properties of inhomogeneous layers. ► We identify different mechanisms that control the surface-induced anisotropy. ► We show that inhomogeneous layers possess different effective refractive indices for s- and p-polarizations. ► We describe the morphological parameters controlling the uniaxial behavior. ► The results are relevant for engineering anisotropic properties in metamaterials operating in the optical regime.
