Measurements results of spectra of permittivity, permeability, reflection, transmission and absorption coefficients of polymer composite with nanosized filler are presented. Material absorbs electromagnetic waves intensively at superhigh and extremely high frequencies.
This paper presents the results of investigation of complex permittivity of composite materials based on carbon nanotubes. Values of the real and imaginary parts of dielectric constant are not monotonically dependent on the concentration and quantity of the CNT walls.
Results of measurements of permeability, permittivity and radio absorption properties of composites on basis of R-10 grade carbonyl iron are presented in this paper. Possibility of formation of radio absorption coating with specified reflection coefficient at frequency band least octave is shown for double-layer composite material with different concentration of carbonyl iron in microwave and extremely...
