Étude du comportement electromagnétique, sous champ magnétique, du composite PVC-Fe3O4 dans la bande des 10 GHz

Abstract A reflectometer interfaced with a plotter has been developed in our laboratory. Using this reflectometer we have carried out measurements of ϵμ as a function of the volume fraction of the composite material PVC-Fe 3 O 4 under the influence of a magnetic field. The experimental results are then compared to the mixture rules. Further, the moment expansion of the scattering matrix up to the fifth order enables us to determine the size parameter as a function of the volume fraction.
