What is the principle of invisibility cloak?
In 2004, a professor at the University of Tokyo in Japan introduced a wide coat, which can make people "hard to recognize" as long as they wear it.
In fact, this invention called "Invisibility Cloak" is not really invisible, it just uses "visual camouflage" to achieve the purpose that people can't distinguish.
It is composed of reflective substances, and the specific method is to coat a layer of reflective substances on the whole clothes, and the clothes are also equipped with cameras.

Materials:
David Smith, a professor at Duke University, and others said that the key to manufacturing this kind of distorted light wave material is the lattice structure characteristics of the material, not its material composition. Starting from Maxwell's equations, they derived a set of equations that determine the structure of materials, and people can manufacture stealth materials according to this set of equations.
Application field:
Visual stealth materials can be used in the military field to make military facilities and troops "completely disappear" from the eyes of the enemy. Since light waves belong to one kind of electromagnetic waves, materials that can "distort" electromagnetic waves in other bands can also be designed according to their equations. For example, using materials that can distort microwaves in radio communication can reduce the obstacles of some objects to communication.
