Frozen sound: An ultra-low frequency and ultra-broadband non-reciprocal acoustic absorber
The absorption of airborne sound is still a subject of active research, and even more since the emergence of acoustic metamaterials. Although being subwavelength, the screen barriers developed so far cannot absorb more than 50% of an incident wave at very low frequencies (<100 Hz). Here, we explo...
