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…
