The paper investigates the shielding effectiveness (SE) of multilayers composite materials over a wide frequency band. First, several nanocomposite materials are characterized, and behavior laws are deduced up to several GHz. Then different arrangements involving conductive layers and composite layers are compared. Finally, a three-layer arrangement combining a magnetic material and a conductive sheet is shown to provide a high shielding effectiveness from DC to 10 GHz.
