Terahertz stepped wideband absorber based on graphene metamaterials
A stepped graphene metamaterial terahertz absorber is proposed to achieve wideband absorption characteristics. By etching the rectangular groove on the surface of graphene and dynamically adjusting the length and the width of the rectangular groove, we improved the absorptivity up to 0.9475 and obta...
