Multiwall Carbon Nanotubes at RF-THz Frequencies: Scattering, Shielding, Effective Conductivity, and Power Dissipation

Multiwall Carbon Nanotubes at RF-THz Frequencies: Scattering, Shielding, Effective Conductivity, and Power Dissipation

Isolated, infinitely long multiwall carbon nanotubes (MWCNTs) interacting with electromagnetic waves in the microwave and far-infrared frequency regime are analyzed using a semi-classical approach. An expression for the bulk effective conductivity of MWCNTs is obtained, valid up to THz frequencies....

Zusammenfassung:Isolated, infinitely long multiwall carbon nanotubes (MWCNTs) interacting with electromagnetic waves in the microwave and far-infrared frequency regime are analyzed using a semi-classical approach. An expression for the bulk effective conductivity of MWCNTs is obtained, valid up to THz frequencies. The influence of the number of tube walls, the radius of the outermost tube wall, and the presence of a gold core on scattering and shielding is analyzed. Comparisons between metallic MWCNTs, metallic single wall carbon nanotubes (SWCNTs), and metal nanowires are provided.
