Influence of capillarity and gravity on confined Faraday waves

S. Diwakar, Vibhor Jajoo, Sakir Amiroudine, Satoshi Matsumoto, Ranga Narayanan, Farzam Zoueshtiagh

Experiments characterizing the influence of gravity and interfacial tension on Faraday instability in immiscible, confined fluid layers are presented. The variation in interfacial tension was obtained by controlling the temperature of a suitable binary fluid pair while the influence of gravity was…

Zipping-Depinning: Dissolution of Droplets on Micropatterned Concentric Rings

José Encarnación Escobar, Erik Dietrich, S. Arscott, Harold J. W. Zandvliet, Xuehua Zhang, Detlef Lohse

The control of the surface wettability is of great interest for technological applications as well as for the fundamental understanding of surface phenomena. In this article, we describe the dissolution behavior of droplets wetting a micropatterned surface consisting of smooth concentric circular…

Indoor 100 Gbit/s THz data link in the 300 GHz band using fast photodiodes

Vinay Kumar Chinni, Malek Zegaoui, Christophe Coinon, X. Wallart, Emilien Peytavit, Jean-Francois Lampin, P. Szriftgiser, Mohammed Zaknoune, Guillaume Ducournau

This paper presents recent achievements towards 100 Gbit/s data links for future 300 GHz communication systems with the new IEEE 802.15.3d standard. Resonant photodiodes structures, and their application for QAM-16 data links in the THz range are shown in indoor scenario.

Compact Waveguide and Guided Beam Pattern Based on the Whispering-Gallery Mode of a Hollow Pillar in a Phononic Crystal Plate

Weitao Yuan, Jinfeng Zhao, Bernard Bonello, Bahram Djafari-Rouhani, Xiaoqing Zhang, Yongdong Pan, Zheng Zhong

We report on the experimental evidence of the guiding of the lowest order antisymmetric Lamb mode (A0) through a compact waveguide consisting of aligned hollow pillars in between a square-latticed array of solid pillars on a thin slab. We analyze both numerically and experimentally the guiding…

Surface acoustic waves in one-dimensional piezoelectric-metallic phononic crystal: Effect of a cap layer

M. Alami, E. H. El Boudouti, Bahram Djafari-Rouhani, Y. El Hassouani, Abdelkrim Talbi

We study the propagation of transverse acoustic waves associated with the surface of a semi-infinite superlattice (SL) composed of piezoelectric-metallic layers and capped with a piezoelectric layer. We present closed-form expressions for localized surface waves, the so-called Bleustein-Gulyaev (BG…
