Abstract
Metasurfaces are artificial structures that have been demonstrated to possess the ability to manipulate light within a subwavelength spatial region. Here, we explore another unraised functionality of the energy redistribution of a metasurface by tuning the phase difference over a supercell. We also propose a practical nanorod-based design to achieve an anomalous steering reflection using the finite element method simulation. The proposed phenomena have potential applications in ultracompact nanophotonic systems and high-efficiency flat devices.
