Abstract

Generalized Brewster effect is a phenomenon where light of both TE (S-) and TM (P-) polarization transmit through a surface with no reflection for a particular incident angle. Generalized Brewster angle (GBA) in visible and near-infrared (NIR) wavelength region is very useful in many scientific and technical areas of applications. However, it is very rare to find a material having this effect as it demands both dielectric and magnetic response in that wavelength range and usually magnetic response is extremely weak in the optical wavelengths. Here we demonstrate the GBA effect of an anisotropic material composed of highly ordered high aspect ratio aluminium doped zinc oxide (AZO) nanopillar arrays. Along with the experimental demonstration, we also provide a proper numerical analysis to investigate the origin of this effect in the pillar array system which will be useful for many conventional as well as new applications in photonics including protein sensing.
