Acoustic liners for modern aero-engine noise reduction
Attenuating the low-frequency component of aero-engine noise is challenging due to the mass and volume constraints when applying conventional noise mitigation techniques using liners and foams. To ad....

Acoustic meta-surface development
A series of acoustic metasurfaces with periodic structures are proposed using porous materials including meta-based fibrous materials and polymer foam to refract an incidence wave in an anomalous yet ....
