Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today's ...

Wave manipulation involves harnessing and tailoring wave properties to meet specific requirements, driving advancements across a wide range of scientific, industrial, and technological fields. A ...

An international team of researchers showed how a nonlinear elastic metasurface could convert a wave's fundamental frequency to its second harmonic. Structural factors in metasurfaces, like the ...

Acoustic metasurfaces derive their characteristics from the interaction between acoustic waves and specifically designed materials. The field is driven by the desire to control acoustic wave ...

The purpose of this work is to develop an experimental system that would control acoustic artifacts when evaluating the clinical outcome of the noninvasive, ultrasound administered neurostimulation.

Researchers have been pushing the capabilities of materials by carefully designing precise structures that exhibit abnormal properties that can control acoustic or optical waves. However, these ...

Phononic crystals are artificially engineered materials that consist of periodic structures designed to control and manipulate the propagation of phonons, which are quasiparticles representing the ...

New system developed for drilling and production safety in deeper waters. The next generation of Kongsberg Maritime's Emergency Acoustic BOP (BlowOut Preventer) Control System, the ACS500 uses the new ...
