  Controlling and harvesting solar radiation pressure is a significant
challenge, however, there are 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, by tuning the Fermi
level of graphene sheets, the transferred momentum to the metasurface can be
controlled. Our results can provide a suitable platform for optical force
control desired in tunable radiation pressure harvesting, micro vehicles, solar
sailing and optical tweezers.
