Abstract [en]

We utilize an exact analytical approach to investigate the electromagnetic wave propagation across an infinite metamaterial composite with general periodic gradient effective permittivity and permeability. A general analytic solution for the field distribution is obtained for an arbitrary periodic variation of complex refractive index across the structure. The calculation is done for the case of constant impedance across the structure. Arbitrary temporal dispersion and losses are allowed and the model is generally applicable to inhomogeneous and anisotropic media simultaneously containing positive and negative refractive index constituents as long as the effective medium approximation is valid.
