Topological surface wave metamaterials for robust vibration attenuation and energy harvesting

Xinyue Wu, Yabin Jin, Abdelkrim Khelif, Xiaoying Zhuang, Timon Rabczuk, Bahram Djafari-Rouhani

We propose topological metamaterials working in Hertz frequency range, constituted of concrete pillars on the soil ground in a honeycomb lattice. Based on the analog of the quantum valley Hall effect, a non-trivial bandgap is formed by breaking the inversion symmetry of the unit cell. A topological...

Equivalence between angular spectrum-based and multipole expansion-based formulas of the acoustic radiation force and torque

Zhixiong Gong, Michael Baudoin

Two main methods have been proposed to derive the acoustical radiation force and torque applied by an arbitrary acoustic field on a particle: The first one relies on the plane wave angular spectrum decomposition of the incident field (see Sapozhnikov and Bailey [J. Acoust. Soc. Am. 133, 661-676 (...

Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen...

Experimental full wavefield reconstruction and band diagram analysis in a single-phase phononic plate with internal resonators

N. Kherraz, M. Radzieński, M. Mazzotti, P. Kudela, F. Bosia, A. S. Gliozzi, D. Misseroni, N. M. Pugno, W. Ostachowicz, M. Miniaci

Research on phononic crystal architectures has produced many interesting designs in the past years, with useful wave manipulation properties. However, not all of the proposed designs can lead to convenient realizations for practical applications, and only a limited number of them have actually been...

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...

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...

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...

Angular characteristics of multipath propagation in an indoor industrial environment

Aliou Bamba, Emmeric Tanghe, Aladji Kamagate, Pierre Laly, Frederic Challita, Adama Konate, Wout Joseph, M. Lienard, Davy Gaillot

The characteristics of multipath components (MPCs) are addressed in an industrial environment at 1.3 GHz by means of measurements with a multidimensional channel sounder. The maximum likelihood estimator, RiMAX, is used to determine the MPCs parameters and takes into account the diffuse scattering...
