This paper studies the electromagnetic behavior of carbon nanotubes (CNTs) based nanocomposites. Such nanocomposites are meaningful for the material design, especially for shielding in EMC applications. A multiscale numerical homogenization method based on a finite element model and incorporating tunneling effect provides is implemented. CNTs are modeled by highly conductive line segments in order to avoid the mesh problems. Effective electrical conductivity is obtained both in statics and time harmonic cases. Numerical predictions are compared to experimental data.
