Acoustic scattering singularities via quasi-Bound states in the continuum
Anis Maddi, Mourad Oudich, Aurelien Merkel +2
Non-Hermitian systems enable advanced control of wave propagation by exploiting engineered losses. This introduces an additional degree of freedom that permits the emergence of exc…
Multi-Channel Amplitude-Phase Asymmetric-Encrypted Janus Acoustic Meta-Holograms
Haohan Zeng, Zhenyu He, Tianxiang Zhang +12
Encrypted optical and acoustic meta-holograms only focus on the encrypted hologram in a single channel, viz. modulating spatial amplitude to project a holographic image. In this re…
Hybrid ultrathin metasurface for broadband sound absorption
Marnix P. Abrahams, Mourad Oudich, Yann Revalor +2
To this day, achieving broadband low-frequency sound absorption remains a challenge even with the possibilities promised by the advent of metamaterials and metasurfaces, especially…
Origin and Customization of Bandgap in Chiral Phononic Crystals
Wei Ding, Rui Zhang, Tianning Chen +6
The wave equation governing the wave propagation in chiral phononic crystals, established through force equilibrium law, conceals the underlying physical information. This has led…
Locally Resonant Metagrating by Elastic Impedance Modulation
Liyun Cao, Sheng Wan, Badreddine Assouar
The optical and acoustic metagratings have addressed the limitations of low-efficiency wave manipulation and high-complexity fabrication of metamaterials and metasurfaces. In this…
Phononic Skyrmions
Liyun Cao, Sheng Wan, Yi Zeng +2
Skyrmions with topologically stable configurations have shown a promising route toward magnetic and photonic materials for information processing due to their defect-immune and low…
