Aluminum Plasmonic Metasurface Enabling a Wavelength-Insensitive Phase Gradient for Linearly Polarized Visible Light

Gao, Song; Yue, Wenjing; Park, Chul-Soon; Lee, Sang-Shin; Kim, Eun-Soo; Choi, Duk-Yong


For conventional phase-gradient metasurfaces, the phase tuning is mostly fulfilled by the exploitation of a nanoantenna- or a Pancharatnam-Berry-phase-based nanoresonator. The former scheme typically suffers from a dispersive phase gradient, while the latter is dispersionless yet functions only for circularly polarized light. The precise reproduction of such sophisticated nanoscale structures, which is essential for applications in color printing, color displays, and image sensing, is...[Show more]
