Design of Environmental Biosensor Based on Photonic Crystal Fiber with Bends Using Finite Element Method

Shyqyri Haxha, Ahmed Teyeb, Fathi Abdel Malek, Emmanuel Kofi Akowuah, Iyad Dayoub

In this paper, a biosensor based on photonic crystal fiber (PCF) is proposed and designed using Full-Vectorial Finite Element Method (FVFEM). The proposed PCF sensor consists of three concentric circles surrounding the core. The key optical sensor characteristics such as sensitivity, the field...

Experimental analysis of Zigbee RF signal performance for railway application: Study on a laboratory reduced scale train

Sara Iben Jellal, O. Cohin, S. Baranowski, Ulrich Biaou, Michael Bocquet, Atika Rivenq

Due to its cost and power performance, Zigbee is widely used and can be applied to railway systems. This paper deals with the performance of a Zigbee (IEEE.802.15.4) RF signal, according to several criteria; this analysis is based on an experimental approach and specially on power measurements in...

Plasticity in memristive devices for spiking neural networks

S. Saïghi, C.G. Mayr, T. Serrano-Gotarredona, H. Schmidt, G. Lecerf, J. Tomas, J. Grollier, S. Boyn, A.F. Vincent, D. Querlioz, S. La Barbera, F. Alibart, Dominique Vuillaume, O. Bichler, C. Gamrat, B. Linares-Barranco

Memristive devices present a new device technology allowing for the realization of compact non-volatile memories. Some of them are already in the process of industrialization. Additionally, they exhibit complex multilevel and plastic behaviors, which make them good candidates for the implementation...

Cristal phononique piézomagnétique à une dimension : contrôle de la propagation par inductance variable

Marie-Fraise Ponge, Jérôme Vasseur, Olivier Bou Matar, Anne-Christine Hladky, Bertrand Dubus

Cette étude concerne un cristal phononique à une dimension constitué d'un empilement de couches piézomagnétiques identiques. Chaque couche est entourée par une bobine connectée à une inductance extérieure. Les ondes élastiques longitudinales se propageant dans cette structure sont étudiées...

A model to predict modal radiation by finite-sized sources in composite plates with account of caustics

Mathilde Stévenin, Alain Lhémery, Sébastien Grondel

The guided wave field generated by finite size transducers in a composite plate is studied. For isotropic plates, Fraunhofer-like approximations can be found in the literature. Similar approximations fail when the plate is anisotropic. A new calculation method is proposed. Based on a modal...

Wave propagation in functionally graded piezoelectric rods with rectangular cross-section

J.G. Yu, Zhang Bo, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of functionally graded piezoelectric material (FGPM) transducers, wave propagation in FGPM structures has received much attention in the past twenty years. But research focused essentially on semi-infinite structures and one-dimensional structures, i.e.,...

Analysis of a Phononic Crystal Constituted of Piezoelectric Layers Using Electrical Impedance Measurement

S.A. Mansoura, Pierre Marechal, Bruno Morvan, Bertrand Dubus

Active materials are investigated as a tuning possibility for phononic crystals. Electromechanical properties of piezoelectric materials electrical and mechanical variables are coupled. Thus, the propagation properties of elastic waves can be tuned using electrical impedance load connected to the...

Cancellation Technique for CW Ground Penetrating Radar Applications

S. Nounouh, Kamel Haddadi, T. Lasri

An adjustable canceller based on microwave interferometry is proposed for ground penetrating radar applications. This canceller, built up with a power divider and an impedance tuner, is integrated in a monostatic continuous wave (CW) radar in order to improve its measurement sensitivity. A set of...
