Abstract

An innovative lightweight and flexible multilayered screen made by electrically doped graphene sheets laminated with thin films of polyethylene terephthalate (PET) is proposed. The shielding effectiveness (SE) of the screen is computed in the low GHz frequency range assuming that the graphene/PET multilayer is modelled as an equivalent single-layer shield having an effective conductivity. A rigorous simulation model is utilized to define the maximum frequency of applicability of the proposed approximate formulation of the SE. A SE of 40 dB is obtained in a wide frequency range, up to more than 200 GHz, with a screen consisting of 24 graphene layers electrically doped and having a total thickness of 0.69 μm.
