Experimental realisation of all-dielectric bianisotropic metasurfaces

Odit, Mikhail; Kapitanova, Polina; Belov, Pavel; Alaee, Rasoul; Rockstuhl, Carsten; Kivshar, Yuri

Description

All-dielectric reciprocal metasurface based on bianisotropic scatterers operating at microwave frequencies is demonstrated experimentally. Experimental studies of a single bianisotropic particle supporting both electric and magnetic Mie-type resonances are performed, and reveal that the particle with a broken symmetry exhibits different back-scattering for the opposite excitation directions. A metasurface composed of the all-dielectric bianisotropic particles is fabricated and experimentally...[Show more]

dc.description.abstractAll-dielectric reciprocal metasurface based on bianisotropic scatterers operating at microwave frequencies is demonstrated experimentally. Experimental studies of a single bianisotropic particle supporting both electric and magnetic Mie-type resonances are performed, and reveal that the particle with a broken symmetry exhibits different back-scattering for the opposite excitation directions. A metasurface composed of the all-dielectric bianisotropic particles is fabricated and experimentally investigated in the frequency range of 4–9 GHz. The measured data demonstrate that the metasurface is characterized by different reflection phases when being excited from the opposite directions. At the frequency 6.8 GHz, the metasurface provides a 2π phase change in the reflection spectrum with the amplitude close to 1.
