WebSep 1, 2024 · Abstract. We report the transmission and reflection properties of graphene-SiO 2, graphene-Si interface with normal incidence. We analyze the real and imaginary parts of Graphene in a broad wavelength range 0.5–4.0 µm and use both Fresnel theory and Finite-difference Time-domain (FDTD) numerical simulations to calculate the … WebApr 8, 2024 · The radiating graphene-based resonating structure remains less efficient [17]. The non-resonating structure of graphene does not contribute to radiation hence antenna can provide high efficiency [18]. In the case of antennas with non-resonating graphene elements, dielectric or metal based resonating structures are being preferred [19, 20].
