Nonlinear measurement of non periodic pulse train with mixer based NVNA dedicated to radar power amplifier

Vincent Bridier, Damien Ducatteau, Maxime Olivier, Hans-Joachim Simon, François Graux, Philippe Eudeline, Gilles Dambrine

A measurement of time domain waveforms using a commercial two ports mixer based NVNA to measure a non periodic repetitive radar pulse train as a periodic one was performed. Then for the first time a 20GHz six port mixer based NVNA able to measure three different frequencies at the same time is…

Fabrication and characterization of 2D phononic crystals based on lithium niobate substrate and nickel pillars

Yu Du, Abdelkrim Talbi, Jean-Claude Gerbedoen, Sergey Yankin, Philippe Pernod, Vladimir Preobrazhensky, Olivier Bou Matar

This work presents experimental investigation of interaction between surface acoustic waves and 2D surface Phononic crystals (PnCs). The PnC is made of 2D array of resonant nickel pillars arranged in different symmetric lattices, and deposited on lithium niobate (Y128 cut) substrate. Measurement of…

Optical properties of nanoporous gallium nitride for photonic applications

Bandar Alshehri

The aim of this research is to characterize the optical properties of a gallium nitride thin film grown on sapphire by MOCVD. Nanoporous of gallium nitride are formed by electrochemical etching. Refractive index, thickness and birefringence are extracted from the nanoporous thin film. Prism…

Impact du recuit d'activation sur la passivation par Al2O3 du silicium type p Cz

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, M. Gauthier, N. Le Quang

L'Al2O3 déposé par ALD est un diélectrique bien connu pour la passivation de surface du silicium type-p. Cependant, une étape de recuit post-dépôt est nécessaire pour activer la passivation. Grâce à des mesures de densités de charges effectives, de défauts d'interface, temps de vie de…

Fabrication of magnetoelastic Bragg reflectors for surface acoustic wave applications and investigation of its tuning with constant magnetic field

Anastasia Pavlova, Sergey Yankin, Abdelkrim Talbi, Jean-Claude Gerbedoen

In this work studying of 1D periodic phononic crystal (PnC) fabrication for 2 GHz and 4 GHz on Ni was done experimentally and theoretically using finite element analysis (FEA). Change of crystal acoustic properties in applied magnetic field was evaluated theoretically.

Effects of Enhanced Image Quality in Infrastructure Monitoring through Micro Aerial Vehicle Stabilization

Chung-Hsin Kuo, Sébastien Kanlanjan, Louis Pagès, Hanadi Menzel, Sascha Power, Chen-Ming Kuo, Christian Boller, Sébastien Grondel

Traditional monitoring of large infrastructure such as towers of churches or for cooling, chimneys or any other type of tall buildings can require extreme effort and hence become very risky and costly since it mainly requires people to be moved around. An interesting alternative in that regard is…

The resonance/thickness prediction of an ultra-thin layer by the low-frequency ultrasound

Gui-Jin Yao, Wei-Jiang Xu, Ke-Xie Wang

A prediction method of the thickness, resonant space and frequency for the two cases of an ultra-thin layer and the narrow-band frequency spectra has been developed without the appearance of the resonance/anti-resonance. Using the characteristic of straight line and the period of π of the layer…

Design of GaN based optical modulator with Mach-Zehnder interferometer structure

R.W. Purnamaningsih, N.R. Poespawati, Irma Saraswati, El Hadj Dogheche

In this work we have designed a Mach Zehnder interferometer (MZI) for electro optic modulator at telecommunication wavelength using GaN on Sapphire. The knowledge of GaN sample optical properties were also investigated, resulting refractive index for the GaN layers were found to be nTE=2.279±0.001…

A fast and functional technique for the noise figure measurement of differential amplifiers

Yogadissen Andee, Jérôme Prouvée, François Graux, Francois Danneville

This paper presents an original technique to measure the noise figure of differential amplifiers with a four-port network analyzer. The approach is fast and simple as the S-parameters and the output noise powers are measured directly with the analyzer. There is no need of hybrid couplers or baluns…
