Abstract

This paper explores building planar transmission lines using carbon nanotube (CNT) networks. Transmission lines with carbon nanotube networks replacing the conventional metallic traces are presented. The experimental realization and the repeated 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 a 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. The effects of CNTs´ bulk density on measured and calculated parameters is explained.
