四季美女摘要：Emerging gradient metasurfaces reprent a new class of diffraction optical components. Through elaborate engineering of planar arrangements of subwavelength optical antennas, metasurfaces are capable of imparting arbitrary pha profiles on to the incident light, thereby enabling devices such as holograms, complex lens, and beam splitters. However, the traditional approach for designing reflective gradient metasurfaces fails for simple beam deflection if the angle included by the incident and the anomalously reflected beam is large. Recently, it has been shown that this shortcoming, which results from the impedance mismatch at the interface and parasitic reflections, can be eliminated by proper metasurface engineering. Here, we report the design, fabrication, and characterization of an optical metasurface, which
