Acoustic Virtual Vortices with Tunable Orbital Angular Momentum for Trapping of Mie Particles
Ғылым және технология
Paper: journals.aps.org/prl/abstract...
Acoustic vortices can transfer angular momentum and trap particles. Here, we show that particles trapped in airborne acoustic vortices orbit at high speeds leading to dynamic instability and ejection. We demonstrate stable trapping inside acoustic vortices by generating sequences of short-pulsed vortices of equal helicity but opposite chirality. This produces a "virtual vortex" with an orbital angular momentum that can be tuned independently of the trapping force. We use this method to adjust the rotational speed of particles inside a vortex beam and for the first time create three-dimensional acoustics traps for particles of wavelength order (so called Mie particles).

Remarkable work. The last 4 seconds of the video are almost unbelievable !
Estimado Ing. Asier Marzo. Soy estudiante de ingeniería electrónica. Estoy impresionado por sus avances científicos, quiero felicitarlo porque me ha inspirado en seguir sus pasos. Desde aquí seguiré cualquier documento que me ayude a realizar pronto un experimento cercano al rayo tractorsónico de su autoría, por ahora es mi mayor propósito. Saludos desde Santiago de Cali, Colombia.
This is a thing of beauty! I hope it wll never cause harm though in the future.
Fascinating.
John Keely work with spherical metal helmoltz resonator, he produced stationnary space/time scalar wave. he explain solar system work.
Just need these on the bottoms of skateboards and vehicles :P Wish you luck :D
See also "rapport CARET", it talk about spatial hard link by using a scalar wave complexe field. very interesting.
Pinta bien la verdad
I wonder if eventually we'll add these tractor beams on the bottom of cars to levitate.
I would like to see some instructions on instructable about this! How many sensor do you use in this setup?
Wow. Isn't it also possible to use it the other way around for artificial defence?
Very cool!I hope someday it will basis for flying vehicles or something like.With respect from Russia;)
How loud are the acoustics? If applied to organic material, would the vibrations tear it apart?

Depends on fragile the material is, but it should be fine for most applications: kzread.info/dash/bejne/q4p4udSQoMSomNI.html

It's supposed to be silent as the object is within the core of the counter rotating "sound tornado" whose 180 degree out of phase sounds, cancel each other out and would also mean there's no stress at all on the body being suspended. Theoretically, the only limit is the amplitude of the sound waves you can make to lift a body. As air can support the weight of heavy aircraft in motion, so ...
Watching the slowed down footage makes me wonder about the cause of rotation and orbit in the planets of our solar system.

No planets. We live on a flat earth.

Future is here
I want to display this device at the Korean Science Museum. Can you share me with the details of the production? I want to have a bigger styrofoam in the air. Currently, it is too small to attract the attention of visitors.
You could try using glycerin drops and see what happens ...

The ball will just drop, we are using little power so it is not dangerous.
Buenas tardes, que referencia es el sensor?
Is there an DIY version? Thx

Jayson Hansen Is this evidence God spoke the universe into existence like the Bible always said?
Buenas noches Asier, habla con oscar larrotta estudiante de ingeniería biomédica de la universidad Manuela Beltrán de Bogotá Colombia, he visto sus vídeos sobre el Rayo sónico y he quedado muy sorprendido, quisiera realizar un proyecto similar para mostrar en mi universidad, con el permiso suyo quisiera saber si me puede ayudar brindándome pautas especificas para lograr crear uno de sus modelos, quedaría muy agradecido con usted. quedare atento a su respuesta

We have released some Instructables that show how to build some acoustic levitators step by step. www.acousticlevitator.com I would recommend "Acoustic Levitator" since it is simple, there are kits available with all the components and can levitate solids as well as liquids. Best of luck.

@@UpnaLab Hello, I happen to be studying your direction -- ultrasonic suspended large particles, and I want to know some details about virtual acoustic vortex in your project.Do you have any publicly available information?In the meantime, would you like to update this link? It won't open
tom delonge has something to do with this i know it.
Genesis 1:3-5 Then God said, “Let there be light”; and there was light. 4 God saw that the light was good; and God separated the light from the darkness. 5 God called the light day, and the darkness He called night. And there was evening and there was morning, one day. Maybe this is why the universe is spinning & not all with the same rotation?
