Abstract
This paper deals with the electrical characterization of a graphene-based material that can be proposed for realizing novel interposers to improve the electrical performance of the electronic packages. The material is a low-cost version of the graphene, realized with commercial graphene nanoplatelets, and thus potentially suitable for a large mass production. An electrical characterization of its complex permittivity in the microwave range is here provided, by using a technique based on the measurement of the scattering parameters on a microstrip-like test vehicle. A Drude model is used to retrieve the values of the equivalent complex permittivity. The results demonstrate that this material may outperform the silicon so far used for interposers.
