Аннотация The efficiency of carbon nanotubes produced by CVD-method on a nickel catalyst at a protection from microwave radiation is shown. These data are confirmed by scanning electron microscopy, energy dispersive X-ray analysis and spectral analysis of the microwave radiation in the frequency range 26-40 GHz. The observed value of the transmission coefficient S21, up to – 42.7 dB, is in agreement with considered possible absorption mechanisms of electromagnetic wave energy in carbon nanoscale systems “CNT-nickel nanoparticles”. The application of carbon powder materials in shielding of electromagnetic radiation has been theoretically justified.
