Tailoring Structure-borne Sound Through Bandgap Engineering in Phononic Crystals and Metamaterials: A Comprehensive Review
Mourad Oudich, Nikhil JRK Gerard, Yuanchen Deng +1
In solid state physics, a bandgap (BG) refers to a range of energies where no electronic states can exist. This concept was extended to classical waves, spawning the entire fields…
Observation of higher-order exceptional points in a non-local acoustic metagrating
Xinsheng Fang, Nikhil JRK Gerard, Zhiling Zhou +7
Higher-order exceptional points have attracted increased attention in recent years due to their enhanced sensitivity and distinct topological features. Here, we show that nonlocal…
Bilayer Photonic Graphene
Mourad Oudich, Guangxu Su, Yuanchen Deng +6
Drawing inspiration from bilayer graphene, this paper introduces its photonic analog comprising two stacked graphene-like photonic crystals, that are coupled in the near-field thro…
Systematic design and experimental demonstration of transmission-type multiplexed acoustic meta-holograms
Yifan Zhu, Nikhil JRK Gerard, Xiaoxing Xia +6
Acoustic holograms have promising applications in sound-field reconstruction, particle manipulation, ultrasonic haptics and therapy. This paper reports on the theoretical, numerica…
Magic-angle Bilayer Phononic Graphene
Yuanchen Deng, Mourad Oudich, Nikhil JRK Gerard +3
Thanks to the recent discovery on the magic-angle bilayer graphene, twistronics is quickly becom11 ing a burgeoning field in condensed matter physics. This letter expands the realm…
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…
