Emulation of end-to-end communications systems in railway scenarios: physical layer results

Juan Moreno Garcia-Loygorri, Sofiane Kharbech, Laurent Clavier, Redha Kassi, Raul Torrego, Aitor Arriola, Inaki Val, Marion Berbineau, Jose Soler, Ying Yan

The complexity of modern communication systems is remarkable, and the efforts needed to put into service a new one arc substantial as well. In some industrial sectors, circumstances are even harder. For example, in railways, the tests to be done are costly due to the integration in the rolling…

Detection and evaluation of macro-cracks and micro-cracking by using automated surface wave non-contact scanners

Charles Ciccarone, Bogdan Piwakowski, Frédéric Skoczylas, Radoslaw Drelich, Jean-Marie Henault

The goal of the presented work is the detection and evaluation of cracks, in the VeRCoRs mock-up which constitutes the double-wall containment building of a Nuclear Power Plant in scale 1/3. The experiments are conducted in situ, on the inner wall of the VeRCoRs mock-up. The detection is performed…

Power measurement setup development for on-wafer characterization at 185-191 GHz

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article presents off-wafer scalar power setup dedicated to load-pull measurement for characterization of on-wafer active devices between 185 and 191 GHz. The system architecture allows us to determine the absorbed input power, the output power delivered to the load, the power added efficiency…

A superheterodyne 300 GHz wireless link for ultra-fast terahertz communication systems

Iulia Dan, Guillaume Ducournau, Shintaro Hisatake, Pascal Szriftgiser, Ralf-Peter Braun, Ingmar Kallfass

A superheterodyne transmission scheme is adopted and analyzed in a 300 GHz wireless point-to-point link. This was realized using two different intermediate frequency (IF) systems. The first uses fast digital synthesis which provides an IF signal centered around a carrier frequency of 10 GHz. The…
