This graphene/gold bilayer metamaterial strategy was used to design and experimentally create a 0.2 terahertz frequency-selective absorber. The proposed device maintained a benchmark high-quality ...

The terahertz band is, at least for now, somewhat of a spectrum oddity, positioned between microwaves and infrared light and roughly spanning from 0.1 THz (100 GHz/3 mm wavelength) to 10 THz (30 μm).
