Abstract: Electrical properties measurement of graphene-based composite materials in the frequency range 1-18 GHz is proposed in this paper. These materials have been prepared by adding different mass percentages ranging from 1 to 40 % of graphene to PVC. The measurement setup is based on the association of an open- ended coaxial probe and a vector network analyzer. A modeling based on a modified calibration one port model and capacitive approach is proposed to relate the measured microwave signal to the complex permittivity and conductivity of the material under test.


Keywords: Dielectric permittivity, Microwave characterization, Open-ended coaxial probe, Graphene, Polymer.
