TL;DR: It is demonstrated that a directed NLOS path scheme will make a terahertz communication system robust to shadowing, and it is shown that dielectric mirrors covering only parts of the walls will significantly enhance the signal coverage in a typical indoor scenario.

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.

TL;DR: In this paper, an omnidirectional mirror for the terahertz range made from polypropylene and high-resistivity silicon is presented. But the structure is characterized by time-domain spectroscopy and the experimental data are in good agreement with transfer matrix calculations.

TL;DR: In this article, the potential of terahertz spectroscopy for contactless and nondestructive inline control of polymeric compounding processes was demonstrated using fiber-coupled terahers.

TL;DR: In this article, the first investigation of plastic weld joints using terahertz waves is presented, which reveals contaminations like metal or sand within the weld joint of two high-density polyethylene sheets.
