Embodiment 1
[0032] From bottom to top, the bottom metal layer Au (mainly for reflection) is a square structure with a side length of 50um and a thickness of 5um. The intermediate dielectric layer is made of Al 2 o 3 The layer is a square structure with a side length of 50um and a thickness of 1.9um. The upper layer is a vanadium dioxide phase change layer with a side length of 50um and a thickness of 2.5um. The upper layer is a graphene adjustable conductance layer. The rate layer is a square structure with a side length of 50um and a thickness of 1um. The top periodic array metasurface layer is an Al layer. Each unit structure is a square and the overall thickness is 1um. The outer length of the square is 6um, the wall thickness is 1.5um, and the inside is I-type resonant columns with the same shape but different sizes. The resonant columns are placed symmetrically along the center of the square. There are two types of I-type resonant columns, the larger The I-type resonant column is tw...

The middle dielectric layer or lossy dielectric layer is made of SiO 2 The layer is a square structure with a side length of 60um and a thickness of 1.5um. The upper layer is a vanadium dioxide phase change layer with a side length of 60um and a thickness of 2.5um. The upper layer is a graphene adjustable conductance layer. The rate layer is a square structure with a side length of 60um and a thickness of 0.5um. The top periodic array metasurface layer is an Al layer. Each unit structure is square and the overall thickness is 1um. The outer length of the square is 7um, the wall thickness is 1um, and the interior is I-type resonant columns of different sizes with the same shape. The resonant columns are placed symmetrically along the center of the square. There are two types of I-type resonant columns. The type I resonance column ...
