[Invited] Tunability of electrically controlled piezoelectric phononic crystals

Anne-Christine Hladky, Charles Croënne, Jerome O. Vasseur, Bertrand Dubus

Two devices based on Phononic Crystals (PCs) made of piezoelectric materials are studied: (1) a stack of piezoelectric rods or plates, poled along their thickness, (2) a piezoelectric plate, poled along its thickness, covered by periodic arrays of electrodes on its two faces. These devices exhibit...

Study of the near field from an electro-optic leaky waveguide for application in all-optical analog-to-digital converters

Pierre-Vincent Dugué, Mohammed El Gibari, Jean-Pierre Vilcot, Hong Wu Li

Very high-speed Analog-to-Digital Converters (ADCs) are key components in ultra-wide bandwidth communication and radar systems. New progress of digital processors has made possible processing of 100-Gb/s data. Nevertheless, electronic ADCs are showing a lack in their sampling rate largely due to...

Autocalibration method for guided wave tomography with undersampled data

Tom Druet, Jean-Loup Tastet, Bastien Chapuis, Emmanuel Moulin

This paper presents a baseline-free quantitative method for the imaging of corrosion flaws present in thin plates with under-sampled data. This method is based on the Hybrid Algorithm for Robust Breast Ultrasound Tomography (HARBUT) which is itself inherently baseline-free. However, in order to...

Autler-Townes splitting and acoustically induced transparency based on Love waves interacting with a pillared metasurface

Yuxin Liu, Abdelkrim Talbi, El Houssaine El Boudouti, Olivier Bou Matar, Philippe Pernod, Bahram Djafari-Rouhani

Autler-Townes splitting (ATS) and electromagnetically induced transparency (EIT) are similar phenomena but distinct in nature. They have been widely discussed and distinguished by employing the Akaike information criterion (AIC). However, such work is lacking in acoustic systems. In this work, the...

A new method of dielectric characterization using a genetic algorithm and a coplanar waveguide on bilayer films

Pierre-Vincent Dugué, Mohammed El Gibari, Mathieu Halbwax, Massinissa Hadjloum, Jean-Pierre Vilcot, Hong Wu Li

Fine characterization of the dielectric properties (r and tanδ) of materials in the microwave, and above, domain is a mandatory step to optimize the performance of components working in this frequency range. When reaching the millimeter frequency range, the conventional parallel plate condenser...

Extraction of packaged GaN power transistors parasitics using S-parameters

Loris Pace, N. Defrance, Arnaud Videt, N. Idir, Jean-Claude de Jaeger, Vanessa Avramovic

In order to better predict the high-frequency switching operation of transistors in power converters, parasitic elements of these devices such as resistances, inductances, and capacitances must be accurately evaluated. This paper reports on the characterization of a gallium nitride (GaN) packaged...

A global variational filter for restoring noised images with gamma multiplicative noise

Nacira Diffellah, Zine-Eddine Baarir, Foued Derraz, Abdelmalik Taleb-Ahmed

In this paper, we focus on a globally variational method to restore noisy images corrupted by multiplicative gamma noise. The problem is assumed as a regularization problem in total variation (TV) framework with data fitting term which is deduced by maximizing the a-posteriori probability density (...
