Frozen sound: An ultra-low frequency and ultra-broadband non-reciprocal acoustic absorber [PDF]
Nature Communications, 2023 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 ...

Occurrence rate of ultra-low frequency waves in the foreshock of Mercury increases with heliocentric distance [PDF]
Nat Commun, 2021 Studies of Mercury’s foreshock have analyzed in detail the properties of ultra-low frequency waves. However, an open question remains in regards to understanding favorable conditions for these planetary foreshocks waves. Here, we report that 0.05–0.41 Hz

Ultra low frequency estimation: a neglected apportion [PDF]
Proceedings of the 9th International Conference on Neural Information Processing, 2002. ICONIP '02., 2002 Most frequency estimation techniques exhibit larger estimation errors in the ultra low frequency (ULF) region (0-10 Hz asymptotically) as compared to higher frequency ranges. This paper examines this situation and proposes to model the estimation errors through function approximation thereby making a priori error estimates available for new signals ...
