【 摘 要 】

In recent years, carbon nanotubes have been the focus of much investigation.One emerging area of this research is applying carbon nanotube materials in microwave devices, particularly for sensing applications.In this thesis, a brief overview of carbon nanotubes is given, along with a survey of some current research in applying carbon nanotube materials in microwave sensing applications.A bottleneck on this kind of research is often the high variability of the electromagnetic properties in carbon nanotube materials.A new characterization method is derived to determine the bulk electromagnetic properties of vertically aligned carbon nanotube forests.This new method is presented along with preliminary validation results.
