Webb1 feb. 2024 · Many researchers have been motivated by these results to establish a broad variety of absorbers for the THz (Tao et al. 2008 ), near-infrared (Liu et al. 2010 ), mid-infrared (Aydin et al. 2011 ), and visible spectrum range. This study has been useful in the field of maximum absorption and development for the terahertz range (THz) gadgets. Webb1 sep. 2024 · In this paper, we propose a kind of tunable absorber composed of a periodical single-layer “ǂ” type graphene cross array, a thick SiO 2 spacer and a gold substrate layer, which can achieve the perfect dual band absorption rather than stacking or combining different basic structures, thus the manufacturing difficulty is reduced.
