Stylolites — irregular seams that occur in limestone — have been found to affect how acoustic waves move through rock samples. Laboratory-based insights from KAUST researchers offer an improved ...
Insights into how mixing layers scatter sound waves could further understanding of acoustic sources in open-jet wind tunnel ...
An unexpected breakthrough in sound wave management has been achieved. At ETH Zurich, researchers have discovered a way to guide sound waves in only one direction. Typically, light and sound waves ...
Density of states of phononic crystals consisting of steel cylinders embedded in high-density polyethylene (HDPE), depicted here for σ = 50. Separate calculations were performed for two distinct cases ...
Schematic of a portion of a 2D hierarchical phoxonic crystal with both large scale photonic lattice and a smaller scale phononic lattice inside a cavity resonator in the larger scale lattice. (Image: ...
(Nanowerk News) Researchers at AMOLF, in collaboration with partners from Germany, Switzerland, and Austria, have realized a new type of metamaterial through which sound waves flow in an unprecedented ...
Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical substances. In Applied Physics Letters, by AIP Publishing, researchers from Nanjing ...
