Abstract

This paper presents the design and the trially made examples of the wideband thin electromagnetic absorber with multiple layers of magnetic materials, which will be useful for the walls in houses and office buildings for protection from thee radiated waves from wireless LANs and electronic equipment.. We achieved an absorbing performance of more than 80% at 1.9 GHz, 2.45 GHz and 19 GHz by using a 0.5 mm layer of the epoxy resin containing a carbonyl iron powder and another 2.5 mm layer of epoxy resin containing a ferrite powder
