Modeling and simulation of the electromagnetic properties of composites filled by carbon nanotubes

Low volume percentages of carbon nanotubes are added in insulating resins in order to obtain new lightweight and conductive nanocomposites with improved electromagnetic performances. The properties of such composites are investigated by means of a 3D model in the J-band (5.38-8.18 GHz), X-band (8.2-12.4 GHz) and P-band (12.4-18 GHz) and the numerical data are validated with experimental results. A sensitivity analysis is carried out in order to account the influence of some parameter such as the amount of filler and the dielectric properties of the resin on the electrical behavior of the simulated composites.
