Paper Abstract

The directions of refracted and reflected beams in gradient metasurfaces are governed by the generalized Snell’s law. The metasurface response can also be controlled dynamically by a standing wave formed by two coherent counterpropagating beams. In this work, we study sensing properties of two types of optically controlled metasurfaces. With different ambient dielectrics, the metasurface reveals a shift of coherent absorption spectrum. The thicker the dielectric layer is and the higher its refractive index ise, the more the absorption spectrum moves. Moreover, the intensities of the anomalous scattering light change with the refractive index and thickness of the dielectric layer while the radiation direction is kept unchanged.
