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)…

Bandwidth enhancement in disordered metamaterial absorbers

Jianping Hao, Eric Lheurette, Ludovic Burgnies, Etienne Okada, Didier Lippens

In this letter, we show numerically and experimentally that a positional disorder of a collection of absorbing electromagnetic wave resonators operating in the long wavelength regime dramatically enhances the absorption bandwidth. The demonstration is performed by using single-size ring-shaped thin…

Noise performance of frequency modulation Kelvin force microscopy

Heinrich Diesinger, D. Deresmes, Thierry Melin

Noise performance of a phase-locked loop (PLL) based frequency modulation Kelvin force microscope (FM-KFM) is assessed. Noise propagation is modeled step by step throughout the setup using both exact closed loop noise gains and an approximation known as "noise gain" from operational…

An SVD-aided efficient bit-loading algorithm for MIMO transmission over spatially correlated channels

Imade Fatani, Marie Zwingelstein, Mohamed Gharbi, François-Xavier Coudoux, Marion Berbineau, Marc G. Gazalet

This paper proposes an efficient bit-loading algorithm for Multiple-Input- Multiple-Output transmission over spatially correlated channels with perfect Channel State Information at both link ends. Based onwater-filling principle, the algorithm does not assume the well-known gap approximation and…

Source localisation in a reverberant plate using average coda properties and early signal strength

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad, Lynda Chehami

A statistical reverberation model based on the average distribution of wave packets propagating in a finite plate is described and it is shown that by fitting experimental data to theoretical expressions, either structural or source-related features can be extracted with very few sensors. An…

RF and broadband noise investigation in high-k/metal gate 28-nm CMOS bulk transistor

Francois Danneville, Laurent Poulain, Yoann Tagro, Sylvie Lepilliet, Benjamin Dormieu, Daniel Gloria, P. Scheer, Gilles Dambrine

In order to pursue Moore's law, material engineering has constituted a real focus during the last decade. In particular, the recent introduction of new Gate stack using High-k dielectrics and Metal Gate (H-k/MG) for CMOS was a key point to downscale the 'Equivalent Oxide Thickness'.…

[Invited Review] SU-8 as a material for lab-on-a-chip-based mass spectrometry

S. Arscott

This short review focuses on the application of SU-8 for the microchip-based approach to the miniaturization of mass spectrometry. Chip-based mass spectrometry will make the technology commonplace and bring benefits such as lower costs and autonomy. The chip-based miniaturization of mass…

Modeling light-sound interaction in nanoscale cavities and waveguides

Yan Pennec, Vincent Laude, Nikos Papanikolaou, Bahram Djafari-Rouhani, Mourad Oudich, Said El-Jallal, Jean-Charles Beugnot, José Maria Escalante, Alejandro Martinez

The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical phenomena, ranging from the laser-induced cooling of a micromechanical resonator…

Multiuser phase coded costas signals with improved cross-correlation and partial cross-ambiguity properties

Nadjah Touati, Charles Tatkeu, Atika Rivenq, Thierry Chonavel

Costas codes are a variant of frequency hopping codes that achieve the «thumbtack» auto-ambiguity function needed in radar applications. However, they may show poor cross- ambiguity properties when selected and assigned randomly which makes them poorly adapted to multiuser radar applications. In…
