Terahertz communication technologies are based on the use of a frequency range from 300 GHz up to 3 THz, according to standardization and regulation activities of the IEEE 802.15 IG THz. Graphene, which is characterized by excellent electrical, thermal and mechanical properties, is an attractive choice for EMI shielding applications. New models are proposed for the analysis of the shielding effectiveness of graphene multilayer thin films in the lower THz range taking into account the frequency dependence of the electrical conductivity. Already known models are applied to estimate the optical transmittance. Moreover, transparent substrates coated by graphene multilayer sheets are simulated. The proposed modeling approach is applied to the performance analysis of graphene multilayer thin sheets in the frequency range up to 1 THz.

Abstract
Terahertz communication technologies are based on the use of a frequency range from 300 GHz up to 3 THz, according to standardization and regulation activities of the IEEE 802.15 IG THz. Graphene, which is characterized by excellent electrical, thermal and mechanical properties, is an attractive choice for EMI shielding applications. New models are proposed for the analysis of the shielding effectiveness of graphene multilayer thin films in the lower THz range taking into account the frequency dependence of the electrical conductivity. Already known models are applied to estimate the optical transmittance. Moreover, transparent substrates coated by graphene multilayer sheets are simulated. The proposed modeling approach is applied to the performance analysis of graphene multilayer thin sheets in the frequency range up to 1 THz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
