Abstract: Accurate characterization of surfaces using cantilever-based optical beam deflection (OBD) systems is crucial for obtaining the sample’s “true” topography and its corresponding material ...

Abstract: The metasurface can provide beam deflection by providing phase gradient. In this work, a single-layer small size transmission-type metasurface is used to generate a deflect beam in the ...
