The visible light stealthy device comprises a metamaterial layer which can change a refractive index of incident light randomly, wherein the metamaterial layer comprises n sub nano layers which are respectively a first nano layer, a second nano layer and an Nth nano layer in sequence from outside to inside; the incident light is converted into first refracted light by irradiating first incident light to the first nano layer, then converted into second refracted light by irradiating first refracted light to the second nano layer, and finally converted into emergent light after being irradiated to the Nth nano layer; and the first refracted light and first virtual refracted light rays are positioned on both sides of a first normal, and the second refracted light and second virtual refracted light rays are positioned on both sides of a second normal. The visible light stealthy device is reasonable in structure, has a refractive index changing function, and can carry out stealth treatment on visible light.
Description
Technical field
The present invention relates generally to material and the instrument field of visible light hidden, refers in particular to a kind of visible light hidden device based on variable refractivity principle.
Background technology
Stealth is perhaps one of concept the most ancient in Ancient Fairy-Tales, and Modern Physics scholar exists certain dispute for the thought of invisible clothes or hidden apparatus, and this makes stealth technique become the forward position of scientific research.Conventional existing material violates the optical laws required for contact clothing stealth, therefore designs the hidden apparatus that one has " Meta Materials " function and has great importance.
Summary of the invention
The technical matters that the present invention need solve is: the technical matters existed for prior art, the invention provides a kind of rational in infrastructure, there is variable refractivity function, stealthy visible light hidden device can be implemented for visible ray.
In order to solve the problem, the solution that the present invention proposes is: a kind of visible light hidden device based on variable refractivity principle, and it comprises the metamaterial layer can carrying out any variable refractivity to incident light; Described metamaterial layer comprises n sub-nanometer layer, from being followed successively by the first nanometer layer, the second nanometer layer, N nanometer layer outside to inside; Described incident light by the first incident light beam strikes to described first nanometer layer, negative index through particular design changes first refractive light into, and then incides described second nanometer layer, and then changes the second refract light into, finally incide N nanometer layer, finally change emergent light into.
Described first refractive light and the first virtual refracted ray lay respectively at the both sides of the first normal, and described second refract light and described second virtual refracted ray are positioned at the homonymy of the second normal; Described first virtual refracted ray and described second virtual refracted ray are respectively the refracted ray of the correspondence of orthodox material, described first refractive light and the actual refracted ray of described second refract light corresponding to described metamaterial layer.
Compared with prior art, tool has the following advantages and beneficial effect in the present invention:
(1) the visible light hidden device based on variable refractivity principle of the present invention, is provided with N number of nanometer layer, and has negative index, incident light can be bent arbitrarily, achieve visible light hidden.
(2) the visible light hidden device based on variable refractivity principle of the present invention, can realize the snakelike walking of visible ray, around outgoing after stealthy object.It can thus be appreciated that the present invention is rational in infrastructure, have variable refractivity function, achieve visible light hidden function.

Embodiment
Below with reference to the drawings and specific embodiments, the present invention is described in further detail.
Shown in Fig. 1 and Fig. 2, the visible light hidden device based on variable refractivity principle of the present invention, comprises the metamaterial layer 2 can carrying out any variable refractivity to incident light 1; Metamaterial layer 2 comprises n sub-nanometer layer, from being followed successively by the first nanometer layer 21, second nanometer layer 22, N nanometer layer 23 outside to inside; Incident light 1 incides the first nanometer layer 21 by the first incident light 40, negative index through particular design changes first refractive light 41 into, and then incides the second nanometer layer 22, and then changes the second refract light 42 into, finally incide N nanometer layer 23, finally change emergent light 5 into.
Shown in Fig. 1 and Fig. 2, first refractive light 41 and the first virtual refracted ray 63 lay respectively at the both sides of the first normal 61, and the second refract light 42 and the second virtual refracted ray 64 are positioned at the homonymy of the second normal 62; First virtual refracted ray 63 and the second virtual refracted ray 64 are respectively the refracted ray of the correspondence of orthodox material, first refractive light 41 and the actual refracted ray of the second refract light 42 corresponding to metamaterial layer 2; Be placed with in metamaterial layer 2 and need stealthy stealthy object 3, incident light 1 is walked along snakelike refract light 4 in metamaterial layer 2, and by emergent light 5 outgoing.
Principle of work: first incident light 1 incides the first nanometer layer 21 of metamaterial layer 2, changes first refractive light 41 into, reenters and is mapped in the second nanometer layer 22, change the second refract light 42 into, the like, walking in the path along snakelike refract light 4, finally changes emergent light 5 into; Visible ray in the process of walking, has been walked around stealthy object 3, has been arrived the rear of stealthy object 3; For stealthy object 3, the incident light 1 in its dead ahead becomes the emergent light 5 in dead astern, thus achieves visible light hidden.
