Abstract :
In this paper, we explore building planar transmission lines using carbon nanotube (CNT) networks. We are successful in building the transmission lines and verifying the feasibility of potential planar transmission lines where carbon nanotube networks replace the conventional metallic traces. The experimental realization and the two-port microwave measurements of the proposed transmission lines enable accurate extractions of the fundamental parameters showing percolation effects in CNT networks. The frequency-dependent phase velocity characteristics show dramatic reduction compared to the speed of light in vacuum. The large magnitude of extracted complex permittivity for CNT networks also exhibits its percolation performance.
