Figure 2

The measurement results are obtained under normal incident with x polarized. Black line is SiO2 with a thickness of 50 nm coated on Au film for reference. Red, orange, yellow, green and blue lines indicate the reflectance of metasurfaces with WAu = 1.5 μm, 2.0 μm, 2.5 μm, 3.0 μm, 3.5 μm and 4 μm, respectively. The period is fixed to be Λg = 5 μm.
