Published in 2021 at "Journal of Sound and Vibration"

DOI: 10.1016/j.jsv.2021.116500

Abstract: Abstract A planar swirl-shaped Acoustic Black Hole (ABH) absorber is proposed and investigated in this paper. In addition to the well-known bending wave retarding phenomena, the speed of torsional waves in the curved ABH with… read more here.

Published in 2017 at "Journal of the Acoustical Society of America"

DOI: 10.1121/2.0000634

Abstract: A shaped acoustic beam pattern that directs acoustic energy in the ± 45° direction with depressed acoustic energy at 0° is described. The shape of the beam pattern is controlled by area shading and the… read more here.

Published in 2022 at "Optics letters"

DOI: 10.1364/ol.449822

Abstract: An H-shaped acoustic micro-resonator (AmR)-based quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor is demonstrated for the first time. The H-shaped AmR has the advantages of easy optical alignment, high utilization of laser energy, and reduction in optical… read more here.
