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...

Compact Multi-Band Flexible Antenna for ISM, WLAN, Wi-Fi, and 5G sub-6-GHz Applications

Syed Muhammad Rizvi Jarchavi, Mohsin Iqbal, Mariana Dalarsson, Mohammad Alibakhshikenari, Iyad Dayoub

Design and analysis of a compact multi-band flexible antenna are presented here. The antenna is designed using the flexible substrate material Rogers 5880 and has a compact size of 18mm×18mm×0.254mm. The coplanar waveguide (CPW) fed radiator consists of a rectangular-shaped patch modified using a...

High speed, antenna-enhanced 10.3 μm quantum cascade detector

G. Quinchard, C. Mismer, M. Hakl, J. Pereira, Quyang Lin, Sylvie Lepilliet, V. Trinité, A. Evirgen, Emilien Peytavit, J. Reverchon, Jean-Francois Lampin, S Barbieri, A. Delga

The strong potential of intersubband detectors in the field of mid-infrared photodetection places this technology as a relevant alternative to HgCdTe detectors in the race for ultrafast operation. While their extremely short photocarrier's lifetime opens up possibilities of detection beyond...

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...

Plasticity of Conducting Polymer Dendrites to Bursts of Voltage Spikes in Phosphate Buffered Saline

Corentin Scholaert, Kamila Janzakova, Yannick Coffinier, Fabien Alibart, Sébastien Pecqueur

The brain capitalizes on the complexity of both its biochemistry for neurons to encode diverse pieces of information with various neurotransmitters and its morphology at multiple scales to route different pathways for neural interconnectivity. Conducting polymer dendrites can show similar features...

Bragg's additivity rule and core and bond model studied by real-time TDDFT electronic stopping simulations: The case of water vapor

Bin Gu, Daniel Muñoz-Santiburcio, Fabiana da Pieve, Emilio Artacho, Jorge Kohanoff, Fabrizio Cleri

The electronic stopping power (Se) of water vapor (H2O), hydrogen (H2) and oxygen (O2) gases for protons in a broad range of energies, centered in the Bragg peak, was calculated using real-time time-dependent density functional theory (rt-TDDFT) simulations with Gaussian basis sets. This was done...

Perception of loudness changes induced by a phononic crystal in specific frequency bands

Arthur Paté, Nicolas Côté, Charles Croënne, Jerome O. Vasseur, Anne-Christine Hladky-Hennion

To study the influence of classical phononic crystal (PC) structures on the acoustical characteristics of a sound source, a combined acoustics/perceptual analysis is conducted on a PC specially designed to exhibit several spectral and wave vector properties in different audible frequency ranges....
