Ultrasound is used to detect or heal the internal body organs and refers to sounds above the audible frequency used to detect faults inside the mechanical structure. Depending on the type of waveform, there are two types of ultrasound: longitudinal wave (pressure wave) and transverse wave (shear wave). Until now, using the transverse wave (shear wave) instead of the longitudinal wave used in most ultrasonic equipment has made it possible to perform more precise ultrasonic diagnosis (photograph), but it was almost impossible to make the necessary high efficiency transverse wave.

Recently, Professor Yoon Young Kim/ Department of Mechanical Engineering, Multiscale Mechanics Design,  has discovered a new phenomenon that can be easily generated with high efficiency, namely 'ultrasonic wave conversion resonance phenomenon' (Physical Review Letter, 118, 205901 (2017)) published on May 19 (local time). In addition, the research done by Professor Kim was highlighted in the journal "Physics" and "Focus", which are separate online news media run by the American Physical Society (APS).
