Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals

Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present the realization of the topological valley-protected zero-order antisymmetric (A 0) or symmetric (S 0) and zero-order shear-horizontal (SH 0) Lamb waves at different domain walls based on topologically distinct asymmetric double-sided pillared phononic crystals. The elastic periodic…

Thermal Stability of Oleate‐Stabilized Gd2O2S Nanoplates in Inert and Oxidizing Atmospheres

Clément Larquet, D. Hourlier, Anh-Minh Nguyen, Almudena Torres-Pardo, Andrea Gauzzi, Clément Sanchez, Sophie Carenco

Capping ligands play an important role in the chemistry of nanoparticles synthesized with organic surfactants. This is relevant to a number of device applications where heating may cause major modifications of crystalline nanoparticles including amorphization, surface rearrangements or sintering.…

On a generic theory of the organic electrochemical transistor dynamics

Vasileios Athanasiou, Sébastien Pecqueur, Dominique Vuillaume, Zoran Konkoli

In the recent years, the organic electrochemical transistors (OECT) have attracted considerable attention for biosensing applications due to the biocompatibility of their materials and their low operating voltages. Upon exposure to an electrolyte, the drain current becomes ion-dependent. This can…

Chapter 6 - One-dimensional magnonic crystals

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents examples of bulk and surface magnons of one-dimensional magnonic crystals, called also superlattices. The such man-made crystals considered here are grown out of semiinfinite stacks of two and also three different ferromagnetic slabs. Each slab is modeled by a simple cubic…

Medical video coding based on 2nd-generation wavelets: performance evaluation

Merzak Ferroukhi, Abdeldjalil Ouahabi, Mokhtar Attari, Yassine Habchi, Abdelmalik Taleb-Ahmed

The operations of digitization, transmission and storage of medical data, particularly images, require increasingly effective encoding methods not only in terms of compression ratio and flow of information but also in terms of visual quality. At first, there was DCT (discrete cosine transform) then…

Design of a four-branch optical power splitter based on gallium-nitride using rectangular waveguide coupling for telecommunication links

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, El Hadj Dogheche

This paper reports design of a simple four-branch optical power splitter using five parallel rectangular waveguides coupling in a gallium-nitride (GaN) semiconductor/sapphire for telecommunication links. The optimisation was conducted using the 3D FD-BPM method for long wavelength optical…

Chapter 5 - Surface, interface, and confined slab magnons

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents simple examples of surface, interface, and confined slab magnons. It addresses also magnetic surface reconstructions due to soft surface magnons. The influence of surface-pinning fields on the spin contribution to the thermodynamic properties of a ferromagnet is also presented…

Chapter 3 - Magnon mono-mode circuits: serial loop structures

Housni Al-Wahsh, Abdellatif Akjouj, L. Dobrzynski, Bahram Djafari-Rouhani

In this chapter and in the frame of long-wavelength Heisenberg model, simple magnonic mono-mode circuits are designed to obtain transmission stop (pass) bands where the propagation of spin waves is forbidden (allowed). These simple devices are composed of infinite one-dimensional mono-mode…
