Riassunto
This work is focused on the techniques of design of thin wideband radar absorbers. After the definition and the characterization of metamaterials, the use of lossy materials and frequency selective surfaces in multilayer structures is discussed, analyzing some proposed design found in the literature. To investigate new possible approaches for the design of electromagnetic absorbers, a new frequency selective surface shape, based on Hilbert and Peano space-filling curves, is proposed and integrated in a classic dual layer structure. Finally the use of commercial lossy materials manufactured by Emerson & Cuming, Inc., for the design of multilayer absorber is investigated and optimized.
