Abstract

The shielding effectiveness (SE) has become a fundamental step in testing active or passive electric devices. The Reverberating Chamber (RC) is a well- established method for determining the SE since has the advantage to expose the material to a more realistic environment. In this paper the SEe of electrically large enclosures with a metallic mesh grid in a RC is evaluated. Enclosures made with metallic mesh are considered. In particular, it is shown that the SE of a material is unable to provide complete information for the SEe of an electrically large enclosure made with the same material. Moreover, this latter one is related to the loading conditions within the enclosure itself. Measurements accomplished at RC of the Università di Napoli Parthenope (formerly Istituto Universitario Navale, IUN) confirm the physical soundness of the proposed approach.
