Abstract

Metasurfaces are new, promising ultrathin materials that can enable many novel optical devices due to their ability to act as a discontinuity interface that introduces an abrupt change in amplitude, phase, and sometimes the polarization of the incident light at the wavelength scale. Therefore they can function as flat optical elements. Here, we investigate the anomalous reflection of light for transverse-magnetic (TM) polarization for normal and oblique incidence in the visible regime. We propose gradient phase gap-surface plasmon metasurfaces that exhibit high conversion efficiency (up to ∼97% of total reflected light) to the anomalous reflection angle for blue, green, and red wavelengths at normal and oblique incidence, and where light polarization is unchanged after the reflection.
