Carbon Nanotubes as base Material for Fabrication of Gap Waveguide Components

Research article published in EUROSENSORS 2014, the 28th European Conference on Solid-State Transducers. Abstract: Carbon nanotubes are being used here as a base material for rapid prototyping of a high frequency device. It has been implemented on a ridge gap resonator for 220-325 GHz which has previously been fabricated in Si. Microfabrication with Si has its benefits but it is time consuming when etching high ratio structures. CNT based structures offer a rapid and low cost turnover for prototyping. Measurements comparing the CNT-based structure to a previously made Si structure and simulations are presented. The unloaded Q-values and the loss/mm are presented from simulations, Si-based resonator measurements and CNT-based resonator measurements.
