Acoustic metamaterials enable tailored manipulation of sound waves, yet their extension to aeroacoustic environments remains challenging due to background flow effects. This work investigates spacetime curvature arising from non-uniform flows and spatially varying properties in phase-gradient metasurfaces, providing insight toward robust design of fully integrated aeroacoustic metamaterials.

Abstract
Acoustic metamaterials enable tailored manipulation of sound waves, yet their extension to aeroacoustic environments remains challenging due to background flow effects. This work investigates spacetime curvature arising from non-uniform flows and spatially varying properties in phase-gradient metasurfaces, providing insight toward robust design of fully integrated aeroacoustic metamaterials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
