摘要

Electromagnetic scattering theory has been applied to calculate polarizabilities of finite-length multiwall carbon nanotubes (MWCNTs) in microwave and subterahertz ranges. The influence of the length and diameter of a MWCNT and electron relaxation time on the regime of the MWCNT interaction with an electromagnetic field has been analyzed. Significant screening effect, due to the strong depolarizing field, determines electromagnetic response of the MWCNTs field in a wide gigahertz frequency range. The main features of the gigahertz spectra of effective permittivity and electromagnetic interference shielding efficiencies of a MWCNT-based composite observed previously in experiments have been systematized and theoretically described.
