Metal-insulator-metal systems exhibit a rich underlying physics leading to a high degree of tunability of their spectral properties. We performed a systematic study on a metal-insulator-nanostructured metal system with a thin 6 nm dielectric spacer and showed how the nanoparticle sizes and...

Propagation number in periodic structures considering losses

P. Meresse, Y. Renou, Jerome O. Vasseur, C. Audoly, Anne-Christine Hladky

The development of absorbing or reflecting panels is of interest for underwater acoustic stealth. Most of the time, losses are not considered in the structures studied, specifically in the propagation number determination, despite the fact that most materials used, such as polymer matrices, have...

Two-frequency excitation of single-mode Faraday waves

William R. Batson, Farzam Zoueshtiagh, Raviprasad Narayanan

The purpose of this work is to investigate, for the first time, excitation of Faraday waves in small containers using two commensurate frequencies. This spatial restriction, which is encountered at low frequencies, leads to a wave composed primarily of one spatial eigenmode of the container. When...

A distributed antenna system for indoor accurate WiFi localization

Christophe Loyez, Michael Bocquet, C. Lethien, N. Rolland

Specific infrastructures are a key challenge for indoor geo-localization systems. In particular, an accurate narrowband localization technique using 802.11 g WiFi signals is proposed in this letter. The related system architecture is built on the basis of radio over fiber topology of distributed...

Ultrasonic Adhesion Measurement of Whey Protein Fouling

Nicolas Collier, Dorothée Debavelaere-Callens, Pierre Campistron, Bertrand Nongaillard, Maude Jimenez, Ghassan Alogaili, Pascal Debreyne, Guillaume Delaplace

The knowledge of milk deposit adhesion is a prerequisite for setting innovative operating conditions of processing and strategies of cleaning. Unfortunately, these data are lacking because few methods of characterization of the adhesion quality exist. In this work, an ultrasonic method toward the...

Sound generation by non-synchronously oscillating rotor blades in turbomachinery

Di Zhou, Xiaoyu Wang, Jun Chen, Xiaodong Jing, Xiaofeng Sun

In this paper, the sound generation by non synchronously oscillating rotor blades in axial compressor is investigated with emphasis on establishing an analytical model for the corresponding sound field inside an annular duct. In terms of the present model, it is found that the acoustic frequency...
