Abstract

Nanocomposites loaded with different types of micro/nanofillers are developed and characterized for use in electromagnetic radar absorbing materials with minimum thickness. It is demonstrated that the tailoring of the desired EM properties can be achieved by the proper choice and combination of both the filler and the matrix. In particular, graphene Nanoplatelets dispersed in a bisphenol-A based epoxy matrix feature a loss tangent lower than a few percent and tailored dielectric permittivity. The designed bilayer absorbers entirely made with nanocomposites have thicknesses of 2 mm and 1.5 mm for the X-band and Ku-band respectively.
