This paper deals with the electromagnetic macroscopic modelling of carbon nanotube interconnects and antennas. The conduction electrons of the nanotube are considered as a two-dimensional fluid moving on the surface representing the positive ion lattice. The linearized Euler’s equation describing the fluid motion is used as a macroscopic constitutive relationship to be coupled to Maxwell’s equation. A surface integral formulation coupled to the fluid model is solved numerically using a finite element method. For peculiar geometries, a transmission line model for CNT is derived. The proposed formulations are applied to the study of carbon nanotubes to evaluate the possible applications to interconnects and antennas.
