A modal formulation for the propagation of guided waves in straight and curved pipes and the scattering at their junction

M. El Bakkali, A. Lhémery, V. Baronian, Sébastien Grondel

The well-established semi-analytic finite element (SAFE) method for predicting guided wave propagation in straight guides is extended to deal with curved pipes using curvilinear coordinates system, following developments by Treyssède and Laguerre [J. Sound Vib. 329 1702-16 (2010)] for helical wires…

Optical waveguiding properties into porous gallium nitride structures investigated by prism coupling technique

Bandar Alshehri, Seung-Min Lee, Jin-Ho Kang, Su-Hyun Gong, Sang-Wan Ryu, Yong-Hoon Cho, El Hadj Dogheche

In order to modulate the refractive index and the birefringence of Gallium Nitride (GaN), we have developed a chemical etching method to perform porous structures. The aim of this research is to demonstrate that optical properties of GaN can be tuned by controlling the pores density. GaN films are…

A synthesis of theoretical and experimental study on power line communication over an aircraft tree-shaped network

Virginie Degardin, Pierre Laly, M. Lienard, Pierre Degauque

This paper gives an overview of the theoretical and experimental approach which has been carried out in order to study the feasibility of broadband power line communication in aircraft. The network which has been chosen corresponds to part of a cabin lighting system and whose tree shape…

Guided waves in multilayered plates

Jiangong Yu, Jean-Etienne Lefebvre, Lahoucine Elmaimouni

Conventional orthogonal polynomial approach can solve the multilayered plate only when the material properties of two adjacent layers do not change significantly. This paper developed an improved orthogonal polynomial approach to solve wave propagation in multilayered plates with very dissimilar…

Sensing light and sound velocities of liquids in two-dimensional phoxonic crystals

Samira Amoudache, Rayisa Moiseyenko, Yan Pennec, Bahram Djafari-Rouhani, Antoine Khater, Ralf Lucklum, Rachid Tigrine

We study theoretically the potentiality of dual phononic-photonic (the so-called phoxonic) crystals for liquid sensing applications. We investigate the existence of well-defined features (peaks or dips) in the transmission spectra of acoustic and optical waves and estimate their sensitivity to the…

Comparison of shallow-mesa InAs/AlSb HEMTs with and without early-protection for long-term stability against Al(Ga)Sb oxidation

E. Lefebvre, G. Moschetti, M. Malmkvist, L. Desplanque, X. Wallart, J. Grahn

The fabrication process of InAs/AlSb high electron mobility transistors (HEMTs) has been improved by depositing, after the shallow-mesa isolation of the active area, a thin SiNx-film on the exposed AlGaSb mesa floor. Devices with and without this early-protection against Al(Ga)Sb oxidation have…

Wave propagation in layered piezoelectric rectangular bar : an extended orthogonal polynomial approach

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

Wave propagation in multilayered piezoelectric structures has received much attention in past forty years. But the research objects of previous research works are only for semi-infinite structures and one-dimensional structures, i.e., structures with a finite dimension in only one direction, such…

Longitudinal and transversal polarization switching in strained ferroelectrics

Laurent Baudry, Igor A. Luk'Yanchuk, A. Razumnaya

Using the multicomponent Landau-Devonshire functional we study the field-induced polarization switching in c-oriented ferroelectric phase of epitaxial perovskite film and found that two different regimes are possible: (i) longitudinal switching with change of the polarization modulus and (ii)…
