Abstract

In this work, we will present the results of the reflectance calculations at various polarizations and angle of incidences for multilayered aluminum-doped zinc oxide metamaterials. The optical permittivity data was deduced from ellipsometry measurements of the multilayered AZO/ZnO metamaterials. We found that reflectance for TM polarized light exhibits smooth minimum near ENZ spectral point and sharp increase in magnitude beyond ENZ wavelength. The various multilayered samples analysis shows that reflectance for TM-polarized incident light for samples with lower optical losses lead to a faster transition from zero to high reflectance.
