The open microwave resonator technique with a measuring hole in one of the mirrors was developed for investigation of electromagnetic properties of conductors smaller than 5 mm. It was employed for measurement of the electric and magnetic polarizabilities of the aerogels based on multiwalled carbon nanotubes (MWCNT). MWCNT aerogels showed electric polarizability intermediate with that of the metal conductors and dielectrics with values close to metals within the frequency range studied (8–12 GHz). This characteristic in combination with the lower weight of MWCNT aerogels and rigid structure makes them promising material for such industrial fields as plasmon resonance and acoustic shielding.Spherical MWCNT aerogels with different diameter.
