Before studying stress wave propagation in such waveguide structures as solid rods, bars, plates, hollow cylinders, or multiple layers, it is useful and interesting to review some applicable concepts ...

Histotripsy is a new, FDA-approved, minimally invasive technique that destroys liver tumors using high-frequency ultrasound ...

Ultrasonic levitation — the practice of creating a standing wave between two ultrasonic sources and positioning lightweight objects such that they can float in the pressure minimums between them ...

Ultrasound close ultrasoundSound with a frequency greater than 20,000 Hz (20 kHz). waves have a frequency higher than the upper limit for human hearing - above 20,000 Hertz (Hz). Different species ...

Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component. The output is boolean, that is, the sensor merely detects whether ...

We can’t hear all levels of sounds. Sound waves with very high frequencies are called ultrasound and our ears can’t detect them. Ultrasound waves have multiple uses including: detecting ...

most often sound waves. While a well-known use of this is sonar, ultrasonic sensors can also be put to use to make a radar-like system. This ultrasonic radar project is from [mircemk] who uses a ...

Through nondestructive, high-throughput laser-ultrasonics characterization, the team experimentally demonstrates tunable elastic-wave velocities within microscale materials. They use the varied ...
