Feasibility study of porous aluminum for electromagnetic shielding applications

Abstract

For a very long time, people have noticed that natively existing porous materials have higher stiffness and low specific weight. This has prompted the development of artificial cellular material made from metals, which leads to different porous metals being produced recently. Porous metals have been used widely in construction, aerospace and automobile industries for their light-weight and reasonable mechanical properties. However, very little research work has been carried out to explore the feasibility of extending porous metals in electromagnetic shielding applications.
