Reconfigurable and tunable terahertz electronic devices are promising for various technological applications, for which metamaterials are receiving interest. Here, a graphene/gold bilayer metasurface enables the creation of a frequency-selective absorber with electrical tuning in the 0.1–1 THz range.
