Optomechanics of ultra thin photonic metasurfaces

We show how the ability of metasurfaces to steer and bend light can be harnessed to shape optomechanical forces. We discuss the potential of metasurfaces as ideal platforms for optomechanics because of their large-area and lightweight form. Such metasurface control of optical forces could lead to novel approaches to optical levitation and propulsion at the macro scale.
