Experimental Evidence of the Existence of Bound States in the Continuum and Fano Resonances in Solid-Liquid Layered Media

Madiha Amrani, Ilyasse Quotane, Cécile Ghouila-Houri, El Houssaine El Boudouti, Leonid Krutyansky, Bogdan Piwakowski, Philippe Pernod, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in continuum (BICs) are resonances with zero width (infinite lifetime) without any leakage into the surrounding media. Their fascinating properties and potential applications have attracted a great deal of interest. In this paper, we give an analytical, numerical, and experimental…

15 - Silicon Nanowires and Nanopillars for Photovoltaic

Yan Pennec, Abdellatif Akjouj, Gaëtan Lévêque, Bahram Djafari-Rouhani, L. Dobrzynski

We present simulations on both the optical properties and the efficiency of nanowires (NWs), nanopillars (NPs) and nanocones (NCs) silicon-based solar cells, together with measurements on their associated optical absorption. We address the calculation using Green's function formalism and…

22 - Superluminal, Negative Delay Times and Selective Transmission in Isotropic-Anisotropic Layered Media

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

In this chapter, we investigate the possibility of superluminal and negative delay times for electromagnetic wave propagation in a linear and passive periodic structure consisting of alternating isotropic and anisotropic media. These phenomena are due to the birefringence of the anisotropic layers…

20 - Omnidirectional Bandgaps and Selective Transmission in Layered Photonic Crystals

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

It has been shown that a one-dimensional periodic structure such as a layered photonic crystal can exhibit the property of omnidirectional reflection, which means that any incident wave launched from the vacuum (or from a substrate) will undergo a total reflection at the layered photonic crystal…

Coherent polarization rotation of TeraHertz spintronic emitters with in-plane uni-axial magnetic anisotropy

Geoffrey Lezier, Pierre Koleják, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem, Nicolas Tiercelin

Spintronic TeraHertz emitters using uni-axial anisotropic FeCo/TbCo 2 /FeCo ferromagnetic layers allow the polarization control of the THz emitted wave thanks to the Stoner-Wohlfarth coherent rotation of magnetization when submitted to a magnetic field along hard axis.

A weighted exponential discriminant analysis through side-information for face and kinship verification using statistical binarized image features

Oualid Laiadi, Abdelmalik Ouamane, Abdelhamid Benakcha, Abdelmalik Taleb-Ahmed, Abdenour Hadid

Side-information based exponential discriminant analysis (SIEDA) is more efficient than side-information based linear discriminant analysis (SILDA) in computing the discriminant vectors because it maximizes the Fisher criterion function. In this paper, we develop a novel criterion, named side-…
