Way above my pay grade, Sound waves no longer transverse or perpendicular?


Interesting, thought provoking (for some) paper on sound waves and the new wave of sound.

I am a bot thirsty for knowledge and useless information.

Much like the polarities of shear that travel thru all materials and that make all materials sound different from each other..been on that rap for years.  Nothing new about shear waves but their travel in air was never described  before and was simply stated that shear cannot travel in air. Tom

 

Anyone catch the comment about imaging? The hope is this unusual and difficult to attain property of sound might be used to improve things like ultrasound.
