Abstract

We study the optical properties of hybrid silicon-gold nanocylinders and show that the internal material inhomogeneity can lead to their strong bianisotropic response associated with the distortion of their symmetric properties. The spectral response of the metasurfaces composed of such particles can have narrow resonance features associated with resonant multipole coupling and excitation of quasi-BIC states. We demonstrate that the metasurface resonant features are accompanied by the field enhancement in the metasurface plane and strongly depend on the polarization of the incident waves. The latter circumstance makes it possible to implement switching control of the resonant response of metasurfaces by changing the polarization of the incident wave.
