Nondestructive evaluation of delamination cracks in textile composites by using 3-dimensional reconstruction from acoustical imaging

Wei-Jiang Xu, Yao Xu, Sylvain Treutenaere, Franck Lauro

An acoustical imaging technique performing 3-dimentional (3D) reconstruction and visualization of materials was developed and used to evaluate delamination cracks in textile composites. The method is based on 2-dimentional (2D) mechanical scan combined with ultrasonic A-scan to obtain 3D volumetric…

Transmission of digital data using guided ultrasonic waves in solid plates

Rudy Bahouth, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

Wireless communication systems are widely known particularly in telecommunication field, where simply, information can be transmitted without using any wires or cables. The wireless communication systems are mainly used for mobile communication and networking and not widely adopted in other mediums…

[Invited] Thermoacoustic sound generation model in porous nanomaterials

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Raphael Lardat, Philippe Pernod

Traditional sound generation transducers are using a magnet/coil/membrane system to induce a particle velocity boundary condition to move the air in order to produce sound. Piezoelectric devices are also electromechanical transducer that are also used for sound generation in cases where common…

LT-GaAs-based photomixers with >2 mW peak output power up to 320 GHz

F Bavedila, Etienne Okada, Jean-Francois Lampin, Guillaume Ducournau, Emilien Peytavit

It is shown in this communication that a LT-GaAs photomixer based on an optically resonant cavity is able to generate peak output powers above 2 mW up to 320 GHz when it is driven by optical pulses of 5 ns width at a repetition rate of 10 MHz.

Linearity and robustness evaluation of 150-nm AlN/GaN HEMTs

Mehdi Rzin, Matteo Meneghini, Fabiana Rampazzo, V. Gao Zhan, Carlo de Santi, Riad Kabouche, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

We report on linearity and robustness of AlN/GaN HEMTs with ultra-thin 4 nm AlN barrier for millimeter wave range applications. Static and dynamic I-V characteristics feature high peak transconductance (g mpeak) of 385 mS/mm, and the transconductance exhibits small changes with gate bias. Semi on-…

Modified AFM-tip for Infrared and THz near field microscopy

Tahsin Akalin

Near field microscopy is commonly achieved thanks to the exaltation of the field between a tip and the sample. The free space electromagnetic wave at infrared or THz frequencies is focused in this extremely small area compared to the wavelength. In many cases, the probe is a classical AFM-tip which…

Terahertz pulsed-field magneto-spectrometer at room-temperature

Jean-Francois Lampin, Antoine Pagies, S Barbieri, L. Desplanque, Xavier Wallart, Jeffrey Hesler, Oleksiy Drachenko, Jean Léotin

We have developed a compact pulsed-field THz magneto-spectrometer based on a THz molecular laser and heterodyne detection both at room-temperature. The recently developed continuous-wave THz laser uses mid-IR-pumped ammonia as active medium. The receiver is based on a subharmonic mixer pumped by a…

A Suspended Silicon Terahertz platform with low loss waveguide and high Q Photonic Crystal cavities

Elias Akiki, Mattias Verstuyft, Guillaume Ducournau, Benjamin Walter, Estelle Mairiaux, Marc Faucher, Jean-Francois Lampin, Bart Kuyken, Mathias Vanwolleghem

A high Q optical resonator and ultra-low losses of a silicon suspended waveguide, are experimentally measured and presented, in order to demonstrate the working of a designed photoacoustic terahertz gas sensor presented in our previous work.
