Abstract:
The dielectric properties of polymer composite nanomaterials based on Cole-Cole, Cole-Davidson, and Maxwell-Garnett models in a wide frequency range (from 1 GHz to 50 GHz) have been simulated. The results of numerical experiment for dispersion of the permittivity and the frequency properties of the electronic attenuation of electromagnetic waves (EMW) in composite nanomaterials with polymeric matrices of nonpolar and polar dielectrics are shown. Non-polar dielectric (LDPE) is selected as the base polymer matrix. A virtual material for nanoparticles with dimensions not exceeding 30 nm with conductive materials from 10-2 to 1 S/m has been selected. Based on these results of simulation, the possibility of using polymer composite nanomaterials as radar absorbing coatings for various applications in the MW band is shown.
