Controlling and harvesting solar radiation pressure is a significant challenge, however, there are a few
potential solutions, which are suitable for several key applications. In this study, an electrically tunable
plasmonic metasurface is designed for the visible spectrum. Moreover, the normal and the tangential
optical forces acting on the metasurface are calculated. Whilst presenting high efficiency in the
anomalous reflection, the designed active metasurface provides tunability of optical forces acting on
the metasurface. The metasurface is composed of tapered silver cells embedded on top of the graphene
layer with 20 layers of graphene sheets. Hence, the transferred momentum to the metasurface can be
controlled by tuning the Fermi level of graphene sheets. Our results can provide a suitable platform for
optical force control desired in tunable radiation pressure harvesting, micro vehicles, solar sailing, and
optical tweezers.
