Journal ArticleDOI
Terahertz imaging: applications and perspectives
Christian Jansen,Steffen Wietzke,Ole Peters,Maik Scheller,Nico Vieweg,Mohammed Salhi,N. Krumbholz,Christian Jördens,Thomas Hochrein,Martin Koch +9 more
TL;DR: Terahertz (THz) spectroscopy holds large potential in the field of nondestructive, contact-free testing as mentioned in this paper, and the ongoing advances in the development of THz systems, as well as the appearance of the first related commercial products, indicate that large-scale market introduction of THZ systems is rapidly approaching.
Journal ArticleDOI
Scattering Analysis for the Modeling of THz Communication Systems
R. Piesiewicz,Christian Jansen,Daniel M. Mittleman,Thomas Kleine-Ostmann,Martin Koch,Thomas Kurner +5 more
TL;DR: In this article, the reflectivity of smooth, optically thick materials can be modeled with Fresnel equations and a Rayleigh roughness factor calculated from the measured surface height distribution of the sample under observation.
Journal ArticleDOI
Properties of Building and Plastic Materials in the THz Range
R. Piesiewicz,Christian Jansen,Steffen Wietzke,Daniel M. Mittleman,Martin Koch,Thomas Kurner +5 more
TL;DR: In this paper, the frequency dependent refractive index and absorption coefficient of a variety of common building and plastic materials between 100 and 1000 GHz were measured for the modeling of bound media propagation phenomena including single and multiple reflections, transmission, diffraction and scattering effects.
Journal ArticleDOI
Analyzing sub-100-μm samples with transmission terahertz time domain spectroscopy
TL;DR: In this article, a method for the extraction of material parameters and thickness information from sub-100-μm thin samples using non-differential transmission terahertz time domain spectroscopy was proposed.
Journal ArticleDOI
Thin-film sensing with planar asymmetric metamaterial resonators
TL;DR: In this article, a rectangular asymmetric double split resonator with field confining tips was proposed for thin-film sensors, where the tip at the end of the resonator arms concentrated the field components into a small area.
