Abstract

The concept of nanoscopic-to-macroscopic homogenization of a sculptured thin film (STF) into a unidirectionally nonhomogeneous continuum is presented. The global constitutive properties of linear STFs are connected to the so-called local or reference constitutive properties by rotation dyadics. The local properties are obtained using the Bruggeman formalism for dielectric as well as bianisotropic STFs. Limitations of the presented approach are discussed, and some avenues for further theoretical research are suggested.
