Investigation of a Tunable Ultra‐Broadband Terahertz Absorber Based on Composite‐Patterned Monolayer Graphene
This paper proposes an ultra‐broadband terahertz absorber featuring a composite‐patterned monolayer graphene metasurface. By structurally combining a centrally perforated elliptical array with adjacent slotted strips, the absorber achieves a continuous working band from 2.18 to 6.32 THz, with a relative bandwidth of...
