Bundles of multiwall carbon nanotube interconnects: RF crosstalk analysis by equivalent circuits

The crosstalk analysis among MWCNTs in a complex bundle is performed in the frequency domain in the range up to 100 GHz. Numerical simulations are performed by using both the multiconductor transmission line (MTL) method and reduced-order equivalent models based on the equivalent single conductor (ESC) approach in order to reduce the complexity of the system. Each MWCNT of the bundle is firstly modeled as an ESC; next, the parallel connected ESCs of the bundle are further represented by only one equivalent conductor. The accuracy of the proposed approximation is assessed and discussed. © 2012 IEEE
