Abstract: | This paper investigates the electromagnetic radiation
characteristics of a metallic, large aspect ratio single walled
carbon nanotube antenna in the terahertz frequency region below 12.5
THz. The key features of terahertz pulse have been revealed on the
carbon nanotube antenna in comparison with conventional
photoconductive switching. The terahertz waveforms, radiation power
and their field distributions have been evaluated and are analysed.
The Fourier transformed spectra over the whole frequency range
demonstrate that the carbon nanotube antenna can be used as
radiation source for broadband terahertz applications. |
