A broadband 4-18 GHz active quadrature hybrid

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of a broadband active quadrature hybrid. This novel architecture consists of a traveling wave amplifier with a unique coupling mechanism, providing amplitude flatness and low phase imbalance over the 4 - 18 GHz frequency band. Experimental results validate…

On the two-way diamond relay channel with lattice-based Compress-and-Forward

Anne Savard, Laurent Clavier

This paper focuses on the full-duplex Gaussian two-way diamond relay channel (TWDRC), where two users wish to exchange their messages with the help of two relays, when one relay performs a lattice-based Compress-and-Forward (CF) scheme. The other relay performs either Decode-and-Forward (DF),…

Pressure-driven dynamics of liquid plugs in rectangular microchannels: influence of the transition between quasi-static and dynamic film deposition regimes

Stéphanie Signe Mamba, Farzam Zoueshtiagh, Michael Baudoin

In this paper, we study experimentally and theoretically the dynamics of liquid plugs in rectangular microchannels for both unidirectional and cyclic pressure forcing. In both cases, it is shown that the transition between quasi-static and dynamic film deposition behind the liquid plug leads to a…

Magnonic analogue of electromagnetic induced transparency in detuned magnetic circuit

Abdelkader Mouadili, El Houssaine El Boudouti, Housni Al-Wahsh, Abdellatif Akjouj, Bahram Djafari-Rouhani, L. Dobrzynski

A simple magnetic device consisting of two dangling side stubs grafted at the same site along a waveguide is designed to obtain a magnonic analogue of electromagnetic induced transparency (EIT) resonance. By detuning the lengths of the two stubs, a resonance can be squeezed between two transmission…

Digital complex delta-sigma modulators with highly configurable notches for multi-standard coexistence in wireless transmitters

Razvan-Cristian Marin, Antoine Frappé, Andreas Kaiser

This paper presents a complex delta-sigma modu-lator (CDSM) designed for integration in a digital transmitter chain targeting multi-standard coexistence with nearby receivers. The use of a DSM has the advantage of increased performance in terms of signal-to-noise-ratio in the band of interest.…

Surface acoustic waves in one-dimensional piezoelectric-metallic phononic crystal: Effect of a cap layer

M. Alami, E. H. El Boudouti, Bahram Djafari-Rouhani, Y. El Hassouani, Abdelkrim Talbi

We study the propagation of transverse acoustic waves associated with the surface of a semi-infinite superlattice (SL) composed of piezoelectric-metallic layers and capped with a piezoelectric layer. We present closed-form expressions for localized surface waves, the so-called Bleustein-Gulyaev (BG…

Thin-film adhesion characterization by Colored Picosecond Acoustics

Arnaud Devos, P. Emery

This paper presents some applications of a recent technique so-called the Colored Picosecond Acoustics (APiC) to the characterization of complex stacks of thin films. The technique is a unique combination of optics and acoustics that implements an acoustic pulse-echo technique at the nanoscale…
