In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...

Ultrasonic phased arrays are one of the wonders of the moment, with videos of small items being levitated by them shared far and wide. We’ve all seen them and some of us have even wondered about ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...

There are quite a few rather unconventional methods of propulsion, but perhaps one of the more curious approaches involved Helmholtz resonance, as demonstrated by [Junsun Hwang] et al. with a paper in ...

1. Ultrahaptics uses a phased array of ultrasonic speakers fired at precisely selected intervals so the intersection of the waves hit the hand providing a tiny forceful vibration. Ultrahaptics hasn’t ...

To establish ultrasonic testing and derived technique capability (phased array and time of flight diffraction) focusing on the nuclear applications to facilitate service to the nuclear industry and ...
