The finite element method (FEM), also known as finite element analysis (FEA), is a widely used numerical solution approach for solving problems of wave propagation and vibration. For some complex ...

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 ...

Researchers at MIT have developed a design framework for controlling ultrasound wave propagation in microscale acoustic ...

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 ...

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

MIT innovates a novel framework for controlling ultrasound waves using microscale acoustic metamaterials, advancing computing technologies.

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 ...

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 ...
