Modelling based on Spatial Impulse Response Model for Optimization of Inter Digital Transducers (SAW Sensors) for Non Destructive Testing

Dame Fall, Marc Duquennoy, Mohammadi Ouaftouh, Bogdan Piwakowski, Frédéric Jenot

This study deals with modelling SAW-IDT transducers for their optimization. These sensors are specifically developed to characterize properties of thin layers, coatings and functional surfaces. Among the methods of characterization, the ultrasonic methods using Rayleigh surface waves are...

Ultrasonic Adhesion Measurement of Whey Protein Fouling

Nicolas Collier, Dorothée Debavelaere-Callens, Pierre Campistron, Bertrand Nongaillard, Maude Jimenez, Ghassan Alogaili, Pascal Debreyne, Guillaume Delaplace

The knowledge of milk deposit adhesion is a prerequisite for setting innovative operating conditions of processing and strategies of cleaning. Unfortunately, these data are lacking because few methods of characterization of the adhesion quality exist. In this work, an ultrasonic method toward the...

Tonpilz Underwater Acoustic Transducer Integrating Lead-free Piezoelectric Material

Rémi Rouffaud, Christian Granger, Anne-Christine Hladky, Mai Pham Thi, Franck Levassort

A Tonpilz transducer based on lead-free piezoelectric material was fabricated, modeled and characterized. The stack is composed of two rings of doped BaTiO 3. This composition was initially chosen due to good electromechanical performance (k t at 40%) and high mechanical quality factor (Q m over...

Two-frequency excitation of single-mode Faraday waves

William R. Batson, Farzam Zoueshtiagh, Raviprasad Narayanan

The purpose of this work is to investigate, for the first time, excitation of Faraday waves in small containers using two commensurate frequencies. This spatial restriction, which is encountered at low frequencies, leads to a wave composed primarily of one spatial eigenmode of the container. When...

Degradation assessment of LYRA after 5 years on orbit : Technology Demonstration

A. Benmoussa, B. Giordanengo, S. Gissot, I. E. Dammasch, M. Dominique, Jean-François Hochedez, A. Soltani, Nour Eddine Bourzgui, T. Saito, U. Schühle, A. Gottwald, U. Kroth, A. R. Jones

We present a long-term assessment of the radiometric calibration and degradation of the Large Yield Radiometer (LYRA), which has been on orbit since 2009. LYRA is an ultraviolet (UV) solar radiometer and is the first space experiment using aboard a pioneering diamond detector technology. We show...

Frequency response modeling and optimization of a PIN photodiode based on GaN/InGaN adapted to photodetection at a wavelength of 633 nm

M. El Besseghi, Abdelkader Aissat, Bandar Alshehri, Karim Dogheche, El Hadj Dogheche, Didier Decoster

In this paper, the frequency response calculation and optimization of PIN photodiodes based on GaN/InGaN, suitable for photodetection at the wavelength of 633 nm, are presented. The calculations of the impulse as well as the frequency response are performed using the impulse method. The frequency...

A coupler-free differential noise figure measurement technique without noise source on a two-port network analyzer

Yogadissen Andee, Caroline Arnaud, Philippe Seurre, Francois Danneville

This paper presents a measurement technique for the noise figure of differential amplifiers using commercially-available 2-port network analyzers. It is based on the measurement of the noise wave correlation at the output ports of the differential amplifier. A simple measurement setup is used as...
