3D Meta‐Prisms for Versatile Beam Steering by Hybridizing Plasmonic and Diffractive Effect in the Broadband Visible Regime (Small 34/2021)

3D Meta-Prisms In article number 2100561, Xuefeng Zhang, Zhongyang Li, and co-workers have originally proposed and experimentally demonstrated a unique all-metallic 3D meta-prism design with both width/height-variation. Through hybridizing the localized surface plasmonic resonances and the blazed grating diffraction, it enables polarization-multiplexing or wavelength-multiplexing beam-steering functionalities. By mirror-symmetry arrangement, a multi-functional surface is also demonstrated to exhibit alternatively as a concave/convex/flat mirror.
