We report on the effective optical response of single-and multilayer periodic structures of metallodielectric nanosandwiches on the basis of rigorous, full-electrodynamic calculations by the extended layer-multiplescattering method. It is shown that the complex photonic band structure and the reflec

Abstract
In this paper we present a novel procedure for predicting the effective constitutive parameters of threeβdimensional periodic materials with chiral component phases. The method combines the mathematical homogenization technique and the finite element method. The homogenization is accomplished by solving a local problem in the unit cell.

## Abstract Effective electric permittivity and magnetic permeability for metamaterial structures are extracted from 3D field simulation data. The equivalent representation of the metamaterial is a homogeneous slab described with parameterized dispersive Drude and Lorentz models. The parameters of
