A Carbon nanotubes ridge gap resonator

Paper in proceedings, 2013

The extra ordinary electronic properties of carbon nanotubes have made them a highly attractive material for applications like interconnects and microwave electronics. Their quick fabrication process has given them further advantage to be chosen as a first material for these applications. In this paper we present a novel process to fabricate a microwave device using carbon nanotubes not as the main active part but as a core material coated with a 1 μm aluminum layer. A carbon nanotube based ridge gap resonator was fabricated and demonstrated for the first time for the frequency range 200-325GHz. The process is not limited to these frequencies and enables the fabrication of gap wave based device using carbon nanotubes as core for a wide range of frequencies and applications.
