Abstract :
The paper deals with an efficient and accurate circuit-oriented model of multilayer graphene sheet in finite-element method (FEM) by impedance network boundary conditions (INBCs). The INBCs have been developed in the past to model efficiently the field penetration through thin conductive shields. Here, INBCs are used to model graphene sheet by an original and simple circuit-oriented FEM model. The efficiency of the method is proven by validation in different test configurations available in litterature. The proposed circuit-oriented FEM model seems to be very suitable to model next generation smart materials using graphene.
