Anisotropic materials can comprise multilayer stacks, where each anisotropic layer is, in turn, made from uniaxial-uniaxial or uniaxial-isotropic materials. Each uniaxial layer can be made from two dissimilar isotropic materials, e.g., a metal and a dielectric. Similar to usual metallo-dielectric structures, these multilayer structures can be used to achieve unique optical filters, and can be modeled as a bulk structure using effective medium theory. The optical properties of these anisotropic media can be described in terms of effective parameters such as permittivity and permeability tensors. In this work, optical propagation through such layered media is analyzed using Berreman 4 × 4 matrix along with appropriate boundary conditions. Reflection and transmission are investigated as functions of the incident angle and wavelength. Results are compared with those obtained using the transfer matrix approach. This analysis can be extended to Gaussian beam propagation through such anisotropic materials using angular plane wave approach.
