Metal foams are highly versatile new materials with interesting structural and electromagnetic properties. In this work, their use in electromagnetic shielding problems is investigated. More specifically, the shielding effectiveness of an aluminium foam slab is studied on the basis of an effective medium approach. Furthermore, the suitability of using a plasma model in order to describe the electromagnetic behaviour of metal foams is demonstrated by comparison with experimental data.
