Broadband electromagnetic absorbing structures made of graphene/glass-fiber/epoxy composite
Radar-absorbing structures (RASs) with improved mechanical properties and subwavelength thickness are of particular interest for aerospace applications and electromagnetic (EM) interference control. This article proposes a new RAS, made of a graphene-filled lossy laminate (LL) with impedance adapter, having a total thickness less than 4 mm and a normalized absorption bandwidth of 84% in the frequency range 6-18 GHz.
