Non-Hermitian skin effect in a phononic beam based on piezoelectric feedback control

Yabin Jin, Wenxin Zhong, Runcheng Cai, Xiaoying Zhuang, Yan Pennec, Bahram Djafari-Rouhani

Non-Hermitian systems have gained a great deal of interest in various wave problems due their ability of exhibiting unprecedented phenomena such as invisibility, cloaking, enhanced sensing, or the skin effect. The latter manifests itself by the localization of all bulk modes in a specific frequency...

Unstationary dynamics of drops subjected to MHz-surface acoustic waves modulated at low frequency

Philippe Brunet, Michael Baudoin

In the present work, we investigate the unstationary dynamics of sessile droplets subjected to high-frequency surface acoustic waves modulated at a lower frequency close to the first inertio-capillary resonance mode of the drop. Under the action of both acoustic streaming and radiation pressure,...

High Breakdown Field and Low Trapping Effects up to 1400 V in Normally Off GaN‐on‐Silicon Heterostructures

Idriss Abid, Youssef Hamdaoui, Jash Mehta, F Medjdoub

In this study, we report on the development of a fully normally-off high electron mobility transistor (HEMT) gallium nitride on silicon (GaN-on-Si) heterostructures designed for high voltage operation. The normally-off configuration was achieved by means of a p-gallium nitride (p-GaN) cap layer...

CRC-Based Correction of Multiple Errors Using an Optimized Lookup Table

Vivien Boussard, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

In this paper, we propose a new approach to perform multiple error correction in wireless communications over error-prone networks. It is based on the cyclic redundancy check syndrome, using an optimized lookup table that avoids performing arithmetic operations. This method is able to achieve the...

On the Interference Arising From Random Spatial Fields of Interferers Utilizing Multiple Subcarriers

Ce Zheng, Malcolm Egan, Laurent Clavier, Gareth W. Peters, Jean-Marie Gorce

Efective symbol detection, channel estimation and decoding of channel codes require an accurate characterization of the noise probability distribution. In many systems, notably the internet of things, noise is largely in the form of interference, arising from a massive number of simultaneous...

Qualitative analysis of a 3D multiphysics model for nonlinear ultrasonics and vibration induced heating at closed defects

Kevin Truyaert, Vladislav Aleshin, Koen van den Abeele

Upon exciting a material using elastic waves, the locally induced deformation at the interfaces of internally closed defects may cause nonlinear wave mechanics and dynamics in the form of clapping and friction. As a result, both phenomena instigate spectral broadening of the excitation spectrum as...

Exceptional Points and Skin Modes in Non-Hermitian Metabeams

Runcheng Cai, Yabin Jin, Yong Li, Timon Rabczuk, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

We present a non-Hermitian metabeam exhibiting an exceptional point (EP) induced by enforcing parity-time (PT) symmetry through applied external forces. The EP is formed by the hybridization of two flexural wave modes and its output displacement is enhanced by attaching two pillars on top of the...

Facile and secure synthesis of porous partially fluorinated graphene employing weakly coordinating anion for enhanced high-performance symmetric supercapacitor

Ning Cao, Teng Wang, Rabah Boukherroub, Yinghui Cai, Yijiang Qin, Fashun Li, Peng Liu, Qingguo Shao, Mingle Liu, Xiaobei Zang

In this paper, porous partially fluorinated graphene (PFG) for supercapacitors (SCs) was fabricated by a mild and secure one-pot hydrothermal method utilizing weakly coordinating anion BF4− as the fluorine source. The hydrolysis rate of sodium fluoroborate was adjusted by controlling the reaction...
