Abstract
"Micro-wires consisting of bundles of single-wall carbon nanotubes (SWCNTs) having rectangular cross-section above a PEC ground plane are simulated in the high-frequency range. The bundles are modelled as homogeneous conductors characterized by an a.c. effective conductivity given by the Drude frequency dependent expression. The per-unit-length (p.u.l.) impedance is extracted by using the partial-element equivalent circuit (PEEC) approach. Applications to SWCNT-based micro-wires having different configurations are carried out for frequencies up to 103 GHz. Both skin and proximity effects are analysed. The computed frequency spectra of the p.u.l. effective resistance and inductance remain practically constant for frequencies above 100-200 GHz. The comparison with the high-frequency behaviour of copper micro-wires highlights the saturation effect of the SWCNTs bundles."Pubblicazioni consigliate
