Realization of a 2.45 GHz microstrip bandpass filter on a flexible cellulose-based material

Abdelghafour Sid, Pierre-Yves Cresson, Benoit Genestie, Nicolas Joly, Tuami Lasri

In this paper, a bandpass filter realized on a flexible substrate made of a cellulose-based material is presented. The operating frequency band is selected in order to address industrial, scientific and medical (ISM) applications. The bandpass filter central frequency is equal to 2.45 GHz. The...

Experimental and theoretical study of group delay times and density of states in one-dimensional photonic circuit

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present a comparative study of density of states (DOS) and group delay times for a one-dimensional (1D) coaxial photonic crystal made of N cells attached horizontally along a waveguide. Using the interface response theory of continuous media, we derive exact analytical expressions relating the...

4 - Open loop examples

Housni Al Wahsh, L. Dobrzynski, Abdellatif Akjouj, El Houssaine El Boudouti

The simplest general robust zero is the middle of an open loop. When the middles of several free-end open loops of the same length are superposed, their antisymmetric eigenfunctions remain unperturbed and the final network has several degenerate states. The next three examples take into account...

6 - Closed loop and stubs

L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque, El Houssaine El Boudouti

Closed loops with finite open loops attached to the robust zeros of one of their two twin states are the systems investigated in this chapter. Such attached finite loops are called stubs. For simplicity, here only the cases where all the stubs have the same length are considered. This length is...

Enhanced phonon-plasmon interaction in film-coupled dimer nanoridges mediated by surface acoustic waves

Adnane Noual, Rock Akiki, Gaëtan Lévêque, Yan Pennec, Bahram Djafari-Rouhani

The interaction between phonons and localized plasmons in coupled nanoparticles can be exploited both for modulating the scattered electromagnetic field and the understanding of the mechanical vibrations at nanoscale. In this paper, we demonstrate by numerical analysis an enhanced optomechanical...

Wind tunnel integration of Micro-Magneto-Mechanical Systems (MMMS) microvalves for flow control experiments

Thomas Arnoult, Colin Leclercq, Cécile Ghouila-Houri, Aurélien Mazzamurro, Manon Benedito, Romain Viard, Quentin Gallas, Eric Garnier, Denis Sipp, Abdelkrim Talbi, Philippe Pernod

Flow control techniques can be defined as methods changing a flow natural dynamics. The control of a flow can be achieved with actuators affecting the flow momentum. Therefore, a MMMS microvalve was designed and characterized. The micro-actuators have then been integrated to a wind tunnel on the...
