Webb1 feb. 2024 · Graphene-based multi-functional antenna. In order to design an efficient graphene-based multi-functional THz antenna, two switchable CLL-loaded elements as NFRP structures are added around the dipole antenna, as shown in Fig. 3. The distance between the NFRF elements and the dipole antenna with length of d is optimized and … Webb30 aug. 2024 · We report on the ultrafast modulation of a graphene loaded artificial metasurface realized on a SiO 2 /Si substrate by near-IR laser pump, detected via terahertz probe at the resonant frequency of ∼0.8 THz. The results have been acquired by setting the Fermi energy of graphene at the Dirac point via electrostatic gating and illuminating the …

WebbTerahertz (THz) band provides huge bandwidth but the molecular absorptions in these frequencies cause high path losses in long-distance communications. Recently, multi-band ultra-massive MIMO (UM-MIMO) systems based on graphene-based plasmonic nano-antennas have been proposed to overcome the distance problem. Webb9 juli 2024 · Graphene on different substrates, such as SiO2, h-BN and Al2O3, has been subjected to oscillatory electric fields to analyse the response of the carriers in order to explore the generation of terahertz radiation by means of high-order harmonic extraction. The properties of the ensemble Monte Carlo simulator employed for such study have …
