German scientists were able to bend light around a tiny object by using supermatter that surrounded the object. For the first time the phenomenon was demonstrated in XNUMXD
Scientists have revealed for the first time an ability to make objects invisible in all three dimensions. In an article published in the journal Science, scientists said that they were able to use wavelengths close to those visible to the human eye to show details that were hidden behind the bone, thus taking a big step towards making a cloak that makes the wearer see and not be seen - a reality.
The research led by Tolga Ergin from the Karlsruhe Institute of Technology in Germany explains that in the previous attempts to hide objects it was clear that something was hidden there. However, using a "carpet cloak" on top of the bone to eliminate the deformity. "Originally the attempt was to make the object invisible in two dimensions, but the researchers realized that the next step was to use the knowledge of light bending to create a structure that would make three-dimensional objects appear.
Prof. Ortwin Hess from the University of Surrey, who read the scientific article, says that it is impressive by showing "a demonstration of the lack of visibility in three dimensions" but explained that although this is a big step forward to a solution, there is still a great difficulty in making the object disappear from the human eye altogether. "If you look at the table in front of you, you don't see individual atoms because they are very small, you simply see the entire structure - the wood or the plastic," he said, explaining that the technique to hide objects from the human eye would be required to include significantly small components. However, he added, "We won't reach a see-through and invisible cloak that hides people tomorrow, but this demonstration proves that the principle is possible." added

Eyal, without insulting, the option that you are the 'Abel' is greater.
Yoav,
Without insulting, the "I like" option is more appropriate. To be honest, I would guess that you are a teenager, with a head that thinks it's good, but with too much desire to show that you know.
In any case, you have been answered. I will add and say that it is really possible to achieve some effect in the direction, in a more or less good way, with different methods. But all these methods are cumbersome in relation to what is presented here in the article. This is about material. There is no need for computing, an energy source, nothing. Therefore, the result will also be optimal. In other words, an average effect is not expected, but a perfect effect."
This is what you wrote. I quoted you. And like great people, I will also answer you.
First of all, everything in this world requires energy to be realized. You don't have telekinesis, I think, am I right? You move a certain object for example to make it move.
Her cloak of ubiquity makes small objects disappear because the light rays pass around the object, but for a human this possibility is not possible.
We are not little children.
You know the option is not feasible. A small cloak will not be enough to make the person disappear, a tent is needed to make him disappear, in plain sight of course.
Energy is always available in the world, at least for now. If you really want to disappear, you can do it using
His idea. In front of the hot sun no, but in front of a workplace or things like that yes.
Besides, even if they invent such a thing, it's more of a game for children. There is nothing we can do about it. What, we go to work with an invisibility cloak? It will be just another passing toy, which will get tired after a good fifty years.
Eyal, the "cloak" used here is based on changing the refractive index of the material.
Here is a link to the article

Well, a bunch of spies and weapon developers. Why do you even need such a cloak?
It is better to be transparent in the sense of no secrets and no lowly glimpses.
Try to work for a peace economy and not a war economy.
Yoav,
Without insulting, the "I like" option is more appropriate. To be honest, I would guess that you are a teenager, with a head that thinks it's good, but with too much desire to show that you know.
In any case, you have been answered. I will add and say that it is really possible to achieve some effect in the direction, in a more or less good way, with different methods. But all these methods are cumbersome in relation to what is presented here in the article. This is about material. There is no need for computing, an energy source, nothing. Therefore, the result will also be optimal. That is to say, a medium effect is not expected, but a perfect effect.
Did someone say Crysis???
In the original article it was said, to the best of my recollection, that the deflection only occurs at certain angles of up to 60 degrees. And even when you are at the right angle, the detour is not perfect - as was said here, and you can tell that there is something there.
Reminds me of the Predator movie with Arnold Schwarzenegger, where the seeing and unseen animal also disappears but can be seen as something overtaken by light
Yoav, the problem is that a different image should be obtained from every angle, even if you look at the same place on the object. A screen can only display one image, it cannot display a different image for each angle. (maybe only for a few individual angles)
Yoav, something similar to your proposal already exists at the prototype level. These LED screens are not used in projectors, but the principle is the same.
The problem at the root of this "solution" is the enormous computing power required to put it into practice (if we ignore for a moment the high costs of the components and their availability). Computing power that as of today is not yet within reach.
There is something similar to this, but it only works two-dimensionally (when you stand behind at a certain angle you see what is in front of you wearing the cloak) but to say "micro cameras" does not mean that such technology exists..
Sorry for the naivety, but it seems to me that there is a much simpler way of application...
Today it is possible to reduce LED screens to very small sizes. What is the problem with sewing microscopic cameras that will take 360 degree pictures of the environment and translate the image obtained behind the bone to the LED screens? The cameras themselves will be sewn 360 degrees on the entire garment (it is possible that the object screens will also be used as cameras and thus will be used as input for the cameras that are on the other side of the cloak) and thus a XNUMXD image will be obtained and the object will disappear.
The only simple thing that had to be taken care of was that the LED screens would not reflect light, so that the glare of the sun would not hide them.
Am I really sorry or does it sound much simpler?
Such robes have existed in the human imagination a little longer than they have existed in the imaginations of Harry Potter readers.
Well, who said that Rowling's huge parable-Harry Potter is not real? Aha..
But "we" also see beyond the fold.. haha
no chest,
Negative dielectric coefficient. not broken.
On the site bearing the name "Hidan", I would have expected a link to the article, or at least a mention of its name.
For those who do not know:
Methods to control antimatter have long been discovered.
One can assume that the subject will get a serious boost if they invent a time machine.
It has nothing to do with antimatter. This is Meta-material
which is a structure made of "normal" material, but with exotic optical properties (refractive index with a negative value)
It can be assumed that the issue will receive a serious push,
If methods are discovered to control antimatter…
