Researchers integrate waveguide physics into metasurfaces for advanced light control

Caption

Researchers have now achieved high-Q photonic flatbands that span the entire k-space of nonlocal metasurfaces and can be selectively tailored for linearly polarized or circularly polarized light, extending the classic concept of coupled-resonator optical waveguides to metasurfaces.
