[0018] see figure 1 , figure 2 , the first embodiment of a metamaterial in the embodiment of the present invention includes:

[0019] Such as figure 1 As shown, the metamaterial 11 is composed of a substrate 12 and a plurality of artificial microstructure units 13 evenly distributed on the substrate 12, wherein the artificial microstructure unit 13 has at least one artificial microstructure. Such as figure 2 shown in the artificial microstructure 21 and the artificial microstructure 22; wherein the resonant frequencies of the metal structure 21 and the artificial microstructure 22 are different, that is, each has a resonance point;

[0020] The combination of artificial microstructure and substrate can be equivalent to an LC oscillator circuit. When electromagnetic waves are incident, electromagnetic resonance will occur, and different electromagnetic responses will be produced to electromagnetic waves of different frequencies. When electromagnetic waves resonate, because...

Abstract

The embodiment of the invention provides a metamaterial capable of splitting specific single-frequency electromagnetic wave beam in multi-frequency electromagnetic waves. The metamaterial comprises a base plate and a plurality of artificial micro structure units arranged on the base plate, wherein each artificial micro structure unit comprises at least one artificial micro structure, the metamaterial can generate different electromagnetic responses on incidence electromagnetic waves at different frequencies, so the deflection difference of the electromagnetic waves at different frequencies can be caused, the electromagnetic waves is subjected to chromatic dispersion, and the electromagnetic wave beam splitting is realized.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a metamaterial capable of splitting specific single-frequency electromagnetic waves in multi-frequency electromagnetic waves. 【Background technique】 [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have; through the orderly design of the structure on the key physical scale of the material, it is possible to break through the limitations of some apparent natural laws and obtain Metamaterial capabilities beyond the ordinary properties inherent in nature. [0003] The metamaterial is composed of a dielectric substrate and a plurality of artificial microstructure units arranged on the substrate, wherein each artificial microstructure contains an artificial microstructure; the size of each artificial microstructure is generally less than 1 / 10 wavelength, and its external elect...
