Journal ArticleDOI
Terahertz dielectric waveguides
TL;DR: Several classes of nonplanar metallic and dielectric waveguides have been proposed in the literature for guidance of terahertz (THz) or T-ray radiation.
Journal ArticleDOI
THz porous fibers: design, fabrication and experimental characterization
Shaghik Atakaramians,V Shahraam Afshar,Heike Ebendorff-Heidepriem,Michael Nagel,Bernd M. Fischer,Derek Abbott,Tanya M. Monro +6 more
TL;DR: The effective refractive index measured by terahertz time domain spectroscopy shows a good agreement between the theoretical and experimental results indicating a lower dispersion for THz porous fiber compared to THz microwires.
Journal ArticleDOI
Porous fibers: a novel approach to low loss THz waveguides.
TL;DR: This work proposes a novel class of optical fiber with a porous transverse cross-section that is created by arranging sub-wavelength air-holes within the core of the fiber to offer a combination of low transmission loss and high mode confinement in the THz regime.
Journal ArticleDOI
T-Ray Sensing and Imaging

TL;DR: While there are a number of challenges to be overcome there is little doubt that T-ray technology will play a significant role in the near future for advancement of security, public health, and defense.
Journal ArticleDOI
Low loss, low dispersion and highly birefringent terahertz porous fibers
TL;DR: In this article, the authors demonstrate that porous fibers in addition to low loss and high confinement, have near zero dispersion for 0.5-1 THz resulting in reduced terahertz signal degradation compared to microwires.
