Abstract
For the first time different effective medium approximations that are widely used for effective refractive index and form-anisotropy simulations in 2D nanostructures are compared to the plane-wave expansion approach from the point of view of the refractive indices and form-birefringence simulation accuracy. Applicability criteria (porosity and refractive index contrast regions) for the different effective medium models are analyzed on the basis of the comparison to the results obtained by means of the plane-wave expansion approach. It is shown that simplified approaches at certain structural parameters lead to unacceptable inaccuracy of the form-birefringence calculations whereas they give reasonably rough estimates of the effective refractive index.
