Is there an invisibility cloak in the world? Quick, is there really an invisibility cloak in the wor

The so-called "stealth" can not actually avoid the detection of multi-band electromagnetic waves, and the material that can distort one wave is ineffective against other wavelengths of electromagnetic waves. But with some improvements, the effect of visual stealth can be improved.

David Smith, a professor at Duke University, and others say that the key to making such light-wave-distorting materials is the lattice structure of the material, not its material composition. Starting from Maxwell's equations, they deduced a set of equations that determine the structure of materials, which can be used to make stealth materials. Smith said they have the ability to manufacture material that matches the description of their equation within 18 months.

Visual stealth materials can be used in the military field to make military facilities, troops, etc. "completely disappear" from the eyes of the enemy. Since light waves are a type of electromagnetic waves, they can also design materials that can "distort" electromagnetic waves in other bands according to their equations. For example, if a material that can distort microwaves is used in radio communications, it can reduce the impediment of communication by certain objects.

In 2004, a professor at the University of Tokyo in Japan introduced a wide tunic that people could "unrecognizable" just by wearing it. Visual camouflage.

In fact, the invention called the "invisibility cloak" is not really invisible, it just uses "visual camouflage" to achieve the purpose of making people unrecognizable.

It is made up of a retroactive substance, which is coated with a layer of reflective material throughout the garment, and a camera is attached to the garment.

The principle is to shoot the scene behind the garment with a camera, then convert the image to a projector in front of the garment, and then project the image onto the fabric made of a special material.

Today, there are still many theoretical limitations to this material. For example, if you're hiding inside an invisibility cloak, it also means you can't see anything outside. The Smith team is working hard to address this issue.

In addition, Smith also admits that in order not to be detected, the person hiding inside the invisibility suit must be still. Smith explained, "The cloak and what's inside can't change shape, and you can't be invisible if you wear it, waving your arms or walking around.

There are concerns that if large buildings are draped in this material, many people will hit the walls. "It's a bit dangerous, but I think everybody has probably hit a clear glass door at one time or another," Smith said. ”

Yes, it works at night, and you can still see it during the day.

Yes, but it hasn't been rolled out on a large scale.

Quantum stealth digging suit, that is, there is really a "real stealth suit", no one can see the front of the hall when you wear it, "just like no one" I have a bad guy here for many years, I don't know where to buy it, many people have it.

There really is one in the worldInvisibility cloak。A lot of people think that the invisibility cloak isZhejiang UniversityThe kind invented by the teacher, so what kind of invisibility cloak was invented by the teacher at Zhejiang University? Professor Chen Hongsheng of the Department of Information and Telecommunications did invent the invisibility cloak during the experiment, but it was different from what everyone imagined.

It is more appropriate to say that the invisibility cloak here is an invisibility channel, because the material is not clothing, but mainly a hexagonal shape with a side length of about 5 cm.

The core part of the cylindrical body is made of special optical glass.

Explanation of the cloak of invisibility

There was a wonderful ** circulating on the Internet before, an uncle held a piece of cloth that was said to have an invisibility function, and then blocked his body, so people couldn't see him, and they could only see the flowers and trees behind, which couldn't be more magical. Someone mentioned that this is a "domestic quantum stealth suit" designed and produced by a teacher from Zhejiang University.

It is also said that it is a mysterious power that no one knows.

The personnel proposed that ** was cut out, and at the same time put forward the mystery. First shoot Huihong to shoot the background of no one, and then the person takes a green cloth to shoot once, and uses the software to deduct the place of the green cloth, and then after two ** synthesis, there is a magical invisibility cloak effect.

Extended Material: Broadly speaking, world means all, all, everything. Generally speaking, the world refers to the earth on which human beings live.

The world is also referred to as heaven and earth, the world, this shore, the world, all things, the world, and so on. The world can also be interpreted as the sum of perceivable and imperceptible objective beings, as well as the sum of concepts used to describe objective existence and their interrelations, which exist without the transfer of the will of man or other things. The world is made up of the conceptual world and the material world, and the conceptual world contains the sum total of all life's cognition of the objective world and the things that exist to record cognition.

Is there really an invisibility cloak in the world?

Hello dear, glad to answer for you! <>

There is no Shoutong invisibility cloak in the world. However, the so-called "stealth" is only a trick to hide the eyes, in fact, it cannot avoid the detection of multi-band electromagnetic waves, and the excitation material that can distort one wave is ineffective against other wavelengths of electromagnetic waves. However, with some improvements, the effect of visual stealth can be increased.

Then I don't want to be seen in broad daylight, so I can't do anything.

Yes, the pro cannot be done with the current technical means.

There is electromagnetic wave stealth.

People can see objects because they block the passage of light waves. If there is a material applied to the surface of an object that can "walk" around the light waves that are blocked by the object, then the light does not appear to be blocked in any way. To the observer, the object appears to be "non-existent", thus achieving visual invisibility.

The so-called "stealth" is just a trick to cover the eyes, in fact, it cannot avoid the detection of multi-band electromagnetic waves, and the material that can distort one wave is ineffective against other wavelengths of electromagnetic waves. But with some improvements, the effect of visual stealth can be improved.

Principle:

In 2004, a professor at the University of Tokyo in Japan introduced a wide tunic that people could "unrecognizable" just by wearing it. In fact, this invention called "invisibility cloak" is not real stealth, it just uses "visual camouflage" to achieve the purpose of making it impossible to distinguish the scattered knowledge.

It is made of a reflective substance that is void-resistant, and the whole garment is coated with a layer of reflective material, and the garment is equipped with a camera. The principle is to shoot the scene behind the clothes with a camera, then convert the image to a projector in front of the clothes, and then project the image onto the fabric made of a special material.
