Multilayered hyperbolic Au/TiO2 nanostructures for enhancing the nonlinear response around the epsilon-near-zero point
{{output}}
In this work, we present the design, fabrication, and study of the optical properties of multilayered metal-dielectric Au/TiO2 structures. The samples were fabricated using Joule effect evaporation for gold and electron beam evaporation for titanium dioxide. T... ...
