Abstract
Hyperbolic metasurfaces (HMSs) have demonstrated great value for planar and near-field applications. Nevertheless, the ability to engineer a specific HMS design with predefined functionality is still a challenge. Here, we study dozens of HMSs based on gold nanodisks in the visible spectrum and analyze their properties. In particular, we connect the geometric configuration of a metasurface with its spectral hyperbolicity bandwidth and the efficiency of hyperbolic plasmon-polariton canalization. We also analyze the impact of the substrate on the hyperbolic regime of a metasurface. As a result, we derive a universal empirical formula allowing us to obtain the approximate design of a HMS immediately. We provide practical guidelines for designing HMSs that may be used for a plethora of photonic applications.
