Direct imaging of isofrequency contours in all-dielectric optical metasurface

We study the properties of optical surface waves in all-dielectric anisotropic metasurface represented by an array of silicon slabs. We employ back focal plane microscope with solid immersion lens for direct imaging of isofrequency contours of surface waves of the metasurface to reveal both elliptic...

Description
Summary:We study the properties of optical surface waves in all-dielectric anisotropic metasurface represented by an array of silicon slabs. We employ back focal plane microscope with solid immersion lens for direct imaging of isofrequency contours of surface waves of the metasurface to reveal both elliptic and hyperbolic-like regimes and reconstruct the dispersion curves for transverse and longitudinal directions.
