Paper Abstract

We demonstrate reduced reflectance and a corresponding enhancement of transmittance in lamellar hyperbolic metamaterials, with scatterers deposited on the top. The effect is much more significant in curvilinear hyperbolic metamaterials. We also show that absorption strengths of dyes on the top of hyperbolic metamaterials can be tuned and enhanced (nearly threefold). The effect can be controlled by interplay of the substrate geometry, composition and location of the absorbing medium. Our observations pave the way for a variety of applications, including broadband enhancements of light trapping and absorption in solar cells.
