Shielding effectiveness tests of low-cost civil engineering materials in a reverber-ating chamber

In this paper, test study on low-cost civil engineering construction material is presented. In fact, in several civil constructions the strategy is to build up to first fence to EMI that limits interferences while using only in some limited areas high-cost ad hoc shielding material. The materials used in this study are tested at the Universitá di Napoli Parthenope, formerly Istituto Universitario Navale (IUN) Reverberating Chamber (RC) according to a nested approach. Tests are made in the frequency range from 2 to 18 GHz and show that low-cost materials are able to achieve about 16 dB of shielding effctiveness (SE) in contrast to ad hoc materials that show about 50 dB in SE.
