Journal ArticleDOI
Modelling of sub-wavelength THz sources as Gaussian apertures.
TL;DR: The findings show that the shape of the radiation pattern causes a reduction in detectable Thz radiation and hence contributes significantly to low signal-to-noise ratio in THz radiation generation.
Journal ArticleDOI
Through-substrate terahertz time-domain reflection spectroscopy for environmental graphene conductivity mapping
Hungyen Lin,Oliver J. Burton,Sebastian Engelbrecht,Kai-Henning Tybussek,Bernd M. Fischer,Stephan Hofmann +5 more
TL;DR: In this article, the authors demonstrate how terahertz time-domain spectroscopy (THz-TDS) operating in reflection geometry can be used for quantitative conductivity mapping of large area chemical vapor deposited graphene films through silicon support.
Journal ArticleDOI
Towards T-ray spectroscopy of retinal isomers: A review of methods and modelling
TL;DR: In this paper, the status of the retinal chromophore, the work in the area uptil now, and the background of terahertz spectroscopy was reviewed.
Journal ArticleDOI
Determination of the Carbon Nanotube Concentration and Homogeneity in Resin Films by THz Spectroscopy and Imaging
TL;DR: In this paper, the extinction coefficient and refractive index of multi-walled carbon nanotubes (MWNT) embedded in a resin fiber matrix were measured using broadband terahertz time domain spectroscopy.
Journal ArticleDOI
