Hi Ben
We hope to make a barrier using ultrasound, a cross section creation that is powerful enough to hold or keep some of the light in place, enough to see some kind of image or outline of instance of it working. I've read that ultrasound can be used to stop light. Saying that, The type or frequency used wasnt mentioned. Only that ultrasound was used in an array type format. Another section of this topic I've read is the use of Non-reciprocal Brillouin scattering induced transparency which is used for controlling light propagation in a dielectric medium, and for producing slow and fast light, one of the mediums in order for this to work is the air around us. Is there a way of holding the light, even for a minute second using ultrasound in the ways specified above and how exactly would someone go about in doing this. If not, Is there a way of sustaining light in a the air without using fog or a Literal (in your face) material. http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3236.html
Ps. Bristol University | News | December: Haptic shapes using ultrasound - They've created shapes using ultrasound in the air (not vivible ones, touvhable ones) . We want to know that whether using a system similar to the array that is used on the example above, whether the scale is too small or not, can result in the theory becoming a reality.
