Abstract :
Dielectric and conductivity spectra of metal-dielectric composites (epoxy resin with Al and Cu nanoparticles) were studied at high frequencies from 106 to 2 ^109 Hz and analyzed in the model of Cole-Cole relaxation. The experimental and modeled dielectric spectra are used for simulation of reflection, transmission and absorption of the electromagnetic waves in a free space caused by the single- and multilayer composite coatings. Possible microwave applications of the coatings are analyzed and discussed.
