Ultra-foldable/stretchable wideband RF interconnects using laser ablation of metal film on a flexible substrate

Sofiene Bouaziz, Matthieu Berthomé, J.F. Robillard, Emmanuel Dubois

In this paper we demonstrate the feasibility of mechanically flexible and stretchable coplanar waveguide (CPW) transmission lines at millimeter-wave frequencies. Our approach is based on meander horseshoe-shaped CPW line on 125 mu m-thick Polyethylene Naphthalate (PEN) dielectric substrate. The…

Experimental Study of Passive Defect Detection and Localization in Thin Plates from Noise Correlation

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada, Jamal Assaad, Farouk Benmeddour

This paper reports experimental results on a passive imaging technique for structural health monitoring to detect the occurrence of defects in plate-like structures. This technique is based on the fact that the active transient response between two sensors can be passively retrieved by cross-…

Thermal characterization using optical methods of AlGaN/GaN HEMTs on SiC substrate in RF operating conditions

Leny Baczkowski, Jean-Claude Jacquet, Olivier Jardel, Christophe Gaquière, myriam moreau, Dominique Carisetti, Laurent Brunel, Franck Vouzelaud, Yves Mancuso

Performance and reliability of wide bandgap high-power amplifiers are correlated with their thermal behavior. Thermal model development and suitable temperature measurement systems are necessary to quantify the channel temperature of devices in real operating conditions. As a direct temperature…

Design and performances evaluation of new Costas-based radar waveforms with pulse coding diversity

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

Costas codes are a variant of pulse compression waveforms, largely studied for their attractive time-frequency properties. Their 'thumbtack-like' ambiguity function (AF) makes them highly suitable for delay and Doppler estimation, in radar and sonar applications. However, this behaviour…

Reaching the quantum limit of sensitivity in electron spin resonance

A Bienfait, Y Kubo, M Stern, Xin Zhou, T Schenkel, D Vion, D Esteve, B Julsgaard, K Mølmer, P. Bertet, J;j. Pla, C.C. Lo, J.J.L. Morton

The detection and characterization of paramagnetic species by electron spin resonance (ESR) spectroscopy is widely used throughout chemistry, biology and materials science 1 , from in vivo imaging 2 to distance measurements in spin-labelled proteins 3. ESR relies on the inductive detection of…

Numerical simulation of the transient ultrasonic wave reflection at a liquid-solid interface

Nadir Maghlaoui, Hakim Djelouah, Mohamed Ourak, Djema Belgroune

In the nondestructive evaluation domain, the reflection of ultrasonic waves at liquid-solid interfaces generates interesting and useful phenomena when the incident angle approaches the longitudinal critical angle or Rayleigh angle. In this paper, we have developed a model for the study of the…

Acousto-Optical Tunable Transmissive Grating Beam Splitter

Anthony Dieulangard, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

We present a tunable transmissive grating beam splitter for multiple laser line separation based on acousto-optic interaction in tellurium dioxide. Acousto-optic devices are well known for light modulation, frequency shifting, filtration or deflection. For a deflector, the incident light beam is…

Bulk elastic waves with unidirectional backscattering-immune topological states in a time-dependent superlattice

N. Swinteck, S. Matsuo, K. Runge, Jerome O. Vasseur, P. Lucas, P. Deymier

Recent progress in electronic and electromagnetic topological insulators has led to the demonstration of one way propagation of electron and photon edge states and the possibility of immunity to backscattering by edge defects. Unfortunately, such topologically protected propagation of waves in the…

32 Gbit/s QPSK transmission at 385 GHz using coherent fibre-optic technologies and THz double heterodyne detection

Guillaume Ducournau, K. Engenhardt, P. Szriftgiser, D. Bacquet, Mohammed Zaknoune, Rédha Kassi, E. Lecomte, Jean-Francois Lampin

Introduction: Over the last five years, the continuously growing demand for data rates is pushing up the performance of terahertz (THz) devices and systems. Such technologies are strongly envisaged for communication applications [1]. Among the different systems already reported, the highest…
