From: Analysis and design of terahertz reflectarrays based on graphene cell clusters
Variation of the radiated pencil beam for different reflectarrays composed of different cell-cluster dimensions. (a) Cell-cluster composed of 3 × 3 unit-cells. (b) Cell-cluster composed of 6 × 6 unit-cells. (c) Cell-cluster composed of 9 × 9 unit-cells. (d) Cell-cluster composed of 12 × 12 unit-cells. The operating frequency is supposed to be 1 THz and each cell-cluster composed of graphene unit cells with dimensions of 10 × 10 µm.
