Near Field Radiated From Carbon Nanotube Bundles

The near field radiated in the common-mode excitation from single-walled carbon nanotube (SWCNT) bundles with rectangular or hexagonal cross section above a perfect conductive plane is predicted in the gigahertz frequency range using the equivalent single conductor (ESC) method. The risk of electromagnetic interference against nearby components and devices can be estimated. The computed frequency spectra and spatial distributions of the electric and magnetic fields are validated by comparison with the ones radiated from all the conductive SWCNTs in the bundle represented by the multiconductor transmission line (MTL) model. The obtained results highlight the noticeable accuracy and simplicity of the ESC approach with respect to the very time consuming MTL formulation.
