Abstract Microwave shielding and absorbing structures are proposed using composite materials consisting in epoxy-resin and carbon nanopowders fillers up to 10% weight concentration. Characterization in terms of dielectric parameters is performed and discussed and such data are used to optimize the modeling of multilayer electromagnetic absorber by means of in-house built Winning particle optimization algorithm. Experimental validation of mathematical simulations is then performed.

    Highlights ► Paper is focused on the design of electromagnetic absorbing and shielding multilayer structures. ► Structures are based composite materials manufactured using carbon nanotubes. ► Measurements of manufactured materials are in good agreement with numerical simulations. ► High level of shielding effectiveness are obtained with 10% weight concentration of filler.
