WebWe report the performance of a graphene-enhanced THz grating fabricated by depositing a gold layer on the femtosecond micromachined SiO2 substrate. The morphology of the gold plated patterned substrate was studied by scanning electron microscopy (SEM) and atomic force microscopy (AFM), while the quality of the chemical vapor deposition (CVD) … WebA wideband terahertz metal-free absorber is designed and numerically analyzed. The graphite/graphene disks supported by low permittivity dielectric disks are stacked. The stacked graphite disks are placed above a dielectric substrate acting as resonant cavity. The resonance of dielectric cavity is merged with the resonance of a graphite and …
