This innovative research demonstrates how lasers can be used to create and detect high-frequency surface acoustic waves using novel materials as a "wave guide." "The material is considered a soft ...

Some examples of these high-frequency vibrating systems include surface acoustic wave (SAW) filters and ultrasound sensors, such as those used in medical imaging, micro-electromechanical systems ...

"The dynamic strain field of the SAW can be then actively controlled at ultra-high frequency, allowing us to tune the ... Dynamic Local Strain in Graphene Generated by Surface Acoustic Waves, Nano ...

Some examples of such high-frequency vibrating systems are nano-electromechanical systems (NEMS), micro- electromechanical systems (MEMS), as well as ultrasound sensors and surface acoustic wave (SAW) ...

Kim explains how the new measurement was made, “The speed at which surface waves propagate depends on their frequency, which in turn depends on their depth." By measuring changes in velocity in ...

For intense earthquakes, these surface waves can zip around the planet multiple ... the mightiest in the island's recorded history. Yet the frequency of these shakes has declined in recent months ...

This is where two acoustic waves transfer energy to a surface wave by matching its frequency, which in turn causes the surface wave to get larger and more powerful (by increasing its amplitude).

This finding sheds a new light on the most intriguing solar mystery: what makes the sun's atmosphere hotter than its surface ... the energy of these high-frequency waves contributes to the ...
