Experimental study of interaction of electromagnetic radia-tion (EMR) with vertically oriented multiwalled carbon nano-tubes (MWCNT) filled with Fe3С and epoxy composite with random-ly distributed fragments of MWCNT array is carried out. The shielding efficiency and the return loss are measured in the rectangular waveguide for the frequency range from 53.5 to 78.3 GHz. The resonant absorption of millimetre waves is re-vealed at the orthogonal CNT orientation with respect to the EMR electric field within the waveguide. Similar absorption peaks are observed for the epoxy composite. As found, the elec-tromagnetic shielding efficiency varies from 25 to 38 dB (at specimen thickness of 1 mm) depending on the MWCNT orientation with respect to the EMR electric field.
