Laminated Electromagnetic Shielding Effectiveness of Non-Magnetic Materials

This paper presents a simple calculation of the electromagnetic shielding effectiveness of a laminated shield made of conductive non-magnetic sheets. The development of the calculation leads to a simple form of the transfer matrix and the electromagnetic shielding effectiveness shows that at low frequencies the latter is only dependent on the conductivity and the thickness of sheet. Analysis is carried out for the study of the multilayered shield constructed with (Copper-(PANI 44/PU) - Bronze - Aluminum).
