Surface wave seismology has emerged as a critical tool in the investigation of the Earth’s near‐surface structure. Dispersion analysis, which examines the frequency‐dependent velocity of surface waves ...

Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of Regensburg, in ...

The study of earthquakes called Seismology, relies on the fact that different materials within the Earth react differently to stress. When a fault slips, energy radiates outward from the focus (the ...

A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an ...

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can ...

Surface Acoustic Wave (SAW) devices represent a class of sensors that exploit the propagation of acoustic waves through piezoelectric substrates to detect changes in mechanical and environmental ...
