13 - Fibonacci Loop Structures: Bandgaps, Power Law, Scaling Law, Confined and Surface Modes

El Houssaine El Boudouti, Bahram Djafari-Rouhani, Abdellatif Akjouj, L. Dobrzynski

We study theoretically and experimentally the existence and behavior of scaling law, power law, as well as confined and surface modes in one-dimensional (1D) quasiperiodic photonic bandgap structures. These structures are made of segments and loops arranged according to a Fibonacci sequence. We...

9 - Electromagnetic Induced Transparency, Induced Absorption, and Fano Resonances in Photonic Circuits

El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani, Abdelkrim Talbi, L. Dobrzynski

In this chapter, a simple photonic device consisting of two dangling side resonators grafted at two sites (U-shape) or at the same site (cross-shape) along a waveguide is designed in order to obtain sharp resonant states inside the transmission gaps without introducing any defects in the structure...

Cavity flow controlled with an array of magneto-mechanical micro-valves

Thomas Arnoult, Cécile Ghouila-Houri, Colin Leclercq, Aurélien Mazzamurro, Romain Viard, Eric Garnier, Denis Sipp, Alain Merlen, Abdelkrim Talbi, Philippe Pernod

This paper presents and discusses micro-magneto-mechanical valves designed for cavity flow control. Realized using microfabrication techniques and rapid prototyping, the micro-valves exhibit a small footprint and adequate performances for low-speed cavity flow control. An array of 15 micro-valves...

Optimization of Reactive-Ion Etching (RIE) parameters to maximize the lateral etch rate of silicon using SF6/N2 gas mixture: An alternative to etching Si in MEMS with Au components

Munique Kazar Mendes, Cécile Ghouila-Houri, Serria Hammami, Thomas Arnoult, Philippe Pernod, Abdelkrim Talbi

In this work, the effects of the N2 addition to the SF6 plasma used in the isotropic silicon etching of Microelectromechanical systems (MEMS) with Au components are investigated. A four-variables Doehlert design was implemented for optimizing the etching parameters (power, pressure, gas flow rate,...

2 - Closed loop

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

A closed loop can be obtained by linear superposition of the two free ends of an open loop. Its main property is the double degeneracy of its states. The analytical expressions of its eigenvalues, eigenfunctions, and response function are presented. The case of two simultaneous identical measures...

Heuristically accelerated reinforcement learning for channel assignment in wireless sensor networks

Mohamed Sahraoui, Azeddine Bilami, Abdelmalik Taleb-Ahmed

In wireless sensor networks (WSNs), multi-channel communication represents an attractive field due to its advantage in improving throughput and delivery rate. However, the major challenge that faces WSNs is the energy constraint. To overcome the channel assignment problem in an energy-efficient way...
