Exceptional points and skin modes in non-Hermitian elastic phononic beams

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

Exceptional points and skin effect are two hallmarks of non-Hermitian systems combining gain and loss. We demonstrate these phenomena for flexural waves in phononic beams based on applied forces with feedback control. The non-Hermiticity is realized either by means of applying piezoelectric patches…

Performance of PTS reduction technique using a Stepped-Carrier OFDM scheme for JARC applications

Didem Aydogan, Charles Tatkeu, Yassin El Hillali

Orthogonal Frequency Division Multiplexing (OFDM) is a promising option for integrating radar sensing and vehicular communication in the frequency range of 77-81GHz. Although recent publications emphasize benefits of OFDM for achieving reliable radar detection and efficient vehicular communication…

[Review] “Functional upcycling” of polymer waste towards the design of new materials

Olga Guselnikova, Oleg Semyonov, Elizaveta Sviridova, Roman Gulyaev, Alina Gorbunova, Dmitry Kogolev, Andrii Trelin, Yusuke Yamauchi, Rabah Boukherroub, Pavel Postnikov

Diversification of polymer waste recycling is one of the solutions to improve the current environmental scenario. Upcycling is a promising strategy for converting polymer waste into molecular intermediates and high-value products. Although the catalytic transformations into small molecules have…

A Firefly Algorithm for Energy Efficient Clustering in Wireless Sensor Networks

Mohamed Sahraoui, Abdelmalik Taleb-Ahmed

The fundamental metric token by clustering algorithms in Wireless Sensor Networks (WSN) is energy enhancement to maximize network lifetime. One of the crucial issues is network coverage in order to use all of the network’s resources, which increases the lifetime of the network. Moreover, load…

Acoustic dipole surfing on its own acoustic field: toward acoustic quantum analogues

Jean-Paul Martischang, Aymeric Roux, Michael Baudoin

In a recent paper [J. Fluid Mech., 952: A22 (2022)], Roux et al. demonstrated that a translating monopolar acoustic source is subjected to a self-induced radiation force opposite to its motion. This force results from a symmetry breaking of the emitted wave induced by Doppler effect. In the present…

Reprise de croissance MOVPE des contacts ohmiques pour des dispositifs de type HEMT à base de GaN, Ohmic contact regrown by MOVPE for GaN-based HEMT type devices

Charles Pitaval

Les transistors à haute mobilité électronique utilisés dans le domaine des hyperfréquences nécessitent une réduction constante de leurs dimensions et de l'optimisation de leurs caractéristiques électriques. Pour répondre à cette exigence, la reprise de croissance de GaN fortement dopé en…, High electron mobility transistors used in the microwave field require a constant reduction of their dimensions and the optimization of their electrical characteristics. To meet this requirement, the regrowth of highly silicon-doped GaN is applied under the ohmic contact metals. This technique,…
