Pump-probe localization technique of varying solid contacts

Marina Terzi, Lynda Chehami, Maxime Farin, Emmanuel Moulin, Vladislav Aleshin, Nikolay Smagin, Julien de Rosny, Farouk Benmeddour

A baseline-free defect localization method in thin plates is proposed and tested. In this proof-of-concept work, a steel ball pressed against an aluminum plate is used to mimic a surface contact defect. The technique takes benefit of a repetitive nonlinear pump-probe interaction with a...

Fast X‐ray Nanotomography with Sub‐10 nm Resolution as a Powerful Imaging Tool for Nanotechnology and Energy Storage Applications

Vincent de Andrade, Viktor Nikitin, Michael Wojcik, Alex Deriy, Sunil Bean, Deming Shu, Tim Mooney, Kevin Peterson, Prabhat Kc, Kenan Li, Sajid Ali, Kamel Fezzaa, Doga Gürsoy, Cassandra Arico, Saliha Ouendi, David Troadec, Patrice Simon, Francesco de Carlo, Christophe Lethien

In the last decade, transmission X-ray microscopes (TXMs) have come into operation in most of the synchrotrons worldwide. They have proven to be outstanding tools for non-invasive ex and in situ 3D characterization of materials at the nanoscale across varying range of scientific applications....

Design of zero bias power detectors towards power consumption optimization in 5G devices

Issa Alaji, Walid Aouimeur, Haitham Ghanem, Etienne Okada, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This paper presents the design and characterization of zero bias power detectors, based on MOSFET transistors, integrated in SiGe 55-nm BiCMOS technology from ST-Microelectronics. The working frequency bands of the circuits are located in the range (38–55) GHz, dedicated to optimize the power...

Coplanar waveguides on BCB measured up to 760 GHz

Nicolas Zerounian, Walid Aouimeur, Anne-Sophie Grimault-Jacquin, Guillaume Ducournau, Christophe Gaquière, Frédéric Aniel

The integrated THz pattern over any MMIC appears to be a good opportunity to enclose calibration kit suitable for accurate measurements. An original technology based on polymer has been developed. Sub-millimeter single-mode conductor-backed coplanar waveguides using benzocyclobutene polymer and...

Soft fault detection and localization in an unshielded twisted pair network using power line communication

Abdelkarim Abdelkarim, Virginie Degardin, Vincent Cocquempot, Mohamed Amine Atoui

Vehicular electrical wires and communication systems can be affected by faults. Depending on their severity, faults can be divided into two families: hard and soft faults. Hard faults indicate open/short circuits that can lead to serious breakdowns because they prevent the flow of energy or...
