Metagrating-based Single-pixel Acoustic Direction Finding
Thomas Macleod, Sebastian Oberst, David A. Powell +1
Acoustic metamaterials provide new opportunities for compact and efficient wavefront manipulation, extending beyond conventional bulky and power-intensive phased-arrays. In this wo…
The power of dynamic causality in observer-based design for soft sensor applications
William Farlessyost, Sebastian Oberst, Shweta Singh
This paper introduces a novel framework for optimizing observer-based soft sensors through dynamic causality analysis. Traditional approaches to sensor selection often rely on line…
Willis coupling-induced acoustic radiation force and torque reversal
Shahrokh Sepehrirahnama, Sebastian Oberst, Yan Kei Chiang +1
Acoustic meta-atoms serve as the building blocks of metamaterials, with linear properties designed to achieve functions such as beam steering, cloaking and focusing. They have also…
Acoustic radiation force and radiation torque beyond particles: Effects of non-spherical shape and Willis coupling
Shahrokh Sepehrirahnama, Sebastian Oberst, Yan Kei Chiang +1
Acoustophoresis deals with the manipulation of sub-wavelength scatterers in an incident acoustic field. The geometric details of manipulated particles are often neglected by replac…
Scalable Metagrating for Efficient Ultrasonic Focusing
Yan Kei Chiang, Li Quan, Yugui Peng +4
Acoustic focusing plays a pivotal role in a wide variety of applications ranging from medical science to nondestructive testing. Previous works have shown that acoustic metagrating…
Deep learning for brake squeal: vibration detection, characterization and prediction
Merten Stender, Merten Tiedemann, David Spieler +3
Despite significant advances in modeling of friction-induced vibrations and brake squeal, the majority of industrial research and design is still conducted experimentally, since ma…
Acoustic meta-atom with maximum Willis coupling
Anton Melnikov, Li Quan, Sebastian Oberst +3
Acoustic metamaterials are structures with exotic acoustic properties, having promising applications in acoustic beam steering, focusing, impedance matching, absorption and isolati…
Measuring monopole and dipole polarizability of acoustic meta-atoms
Joshua Jordaan, Stefan Punzet, Anton Melnikov +4
We present a method to extract monopole and dipole polarizability from experimental measurements of two-dimensional acoustic meta-atoms. In contrast to extraction from numerical re…
