Abstract
All-dielectric particles with small and large aspect ratio supporting Mie modes and hybrid Mie-Fabry-Pérot modes are experimentally studied in microwave frequency range. The all-dielectric bianisotropic and multimode unidirectional metasurfaces based on such particles are designed and experimentally investigated. We demonstrate the all-dielectric bianisotropic metasurface composed of the particles with broken symmetry exhibits different phase of the reflection coefficient being excited from the opposite directions. The all-dielectric metasurfaces based on the particles with large aspect ratio responsible for the existence of multiple magnetic dipole resonances reveal the multimode unidirectionality when the Kerker conditions are satisfied.
