Observation of ultra-high-Q resonators in the ultrasound via bound states in the continuum
Mohamed Farhat, Younes Achaoui, Julio A. Iglesias Martinez +3
The confinement of waves in open systems represents a fundamental phenomenon extensively explored across various branches of wave physics. Recently, significant attention has been…
Nonlinear coupling of phononic resonators induced by surface acoustic waves
Sarah Benchabane, Aymen Jallouli, Laetitia Raguin +6
The rising need for hybrid physical platforms has triggered a renewed interest for the development of agile radio-frequency phononic circuits with complex functionalities. The comb…
Acoustic radiation-free surface phononic crystal resonator for in-liquid low-noise gravimetric detection
Feng Gao, Amine Bermak, Sarah Benchabane +2
Acoustic wave resonators are promising for gravimetric biosensing. However, they generally suffer from strong acoustic radiation in liquid, which limits their quality factor and in…
Nonlinear effects in locally-resonant nanostrip phononic metasurface at GHz frequencies
Feng Gao, Amine Bermak, Sarah Benchabane +2
In this paper, we report on the observation of nonlinear effects in a nanostrip phononic metasurface (NPM) that enable the tuning of resonance frequencies at 1.42 GHz. The NPM reso…
Wide tailorability of sound absorption using acoustic metamaterials
Aliyasin Elayouch, Mahmoud Addouche, Abdelkrim Khelif
We present an experimental demonstration of sound absorption tailorability, using acoustic metamaterials made of resonant cavities that does not rely on any dissipative material. A…
Subwavelength sound screening by coupling space-coiled Fabry-Perot resonators
A. Elayouch, M. Addouche, M. Farhat +1
We explore broadband and omnidirectional low frequency sound screening based on locally resonant acoustic metamaterials. We show that the coupling of different resonant modes suppo…
