Feasibility study of using porous metal as practical shielding material

This paper presents the feasibility study of using porous metal for electromagnetic shielding purposes. Using the highly porous aluminum (close to 90% porosity) as the material under study, its shielding effectiveness (SE) was studied systematically. A preliminary measurement was carried out to eval...
