Omnidirectional elastic wave attenuation via an isotoxal-star-based auxetic micro-lattice
Nikhil JRK Gerard, Mourad Oudich, Yun Jing
This paper introduces a micro-lattice based metamaterial for low frequency wide-band vibration attenuation, that is enabled by engineering the metamaterial's building blocks to ind…
Study of tantalum and iridium as adhesion layers for Pt/LGS high temperature SAW devices
Thierry Aubert, Omar Elmazria, Badreddine Assouar +6
In this paper, we report on the use of tantalum and iridium as adhesion layers for platinum electrodes used in high temperature SAW devices based on langasite substrates (LGS). Unl…
Space-Time Phononic Crystals with Anomalous Topological Edge States
Mourad Oudich, Yuanchen Deng, Molei Tao +1
It is well known that an interface created by two topologically distinct structures could host nontrivial edge states that are immune to defects. In this letter, we introduce a one…
Bending sound around sharp corners without using topological edge states
Liting Wu, Mourad Oudich, Wenkang Cao +8
Routing and guiding acoustic waves around sharp corners without backscattering losses is of great interest in the acoustics community. Sonic crystals have been primarily utilized t…
