graphene-PET periodic laminate

Transparent graphene-based absorber for next generation wireless 5G technology

The design of new transparent and metal-free absorbers for the upcoming wireless fifth-generation (5G) technology is investigated. To this purpose, innovative absorbers made of graphene-polyethylene terephthalate (PET) laminates separated by PET spacers are proposed. The graphene-PET laminates are modelled as homogeneous single layers characterized by effective conductivities whose values are obtained by means of a new analytical procedure with the aim of optimizing the absorption performances.
