Embodiment 1

[0036] like figure 1 The shown electromagnetic wave polarization control material based on polymer material doping, including host 1, figure 1 The outline is shown in dashed lines in the figure. The main body 1 is composed of a polymer material. The main body 1 is randomly doped with a number of metal particles in the same direction. A gap is formed between adjacent metal particles, and the gap is used for electromagnetic waves. Polarization regulation.

Embodiment 2

[0045] On the basis of Example 1, as figure 2 In the shown electromagnetic wave polarization control material doped with polymer material, the metal particles are metal sheets 3 that do not need to be distributed in the main body 1 and have the same direction.

[0046] When the doped metal particles are metal squares, the polarization control material has two-dimensional properties, such as image 3 As shown, when incident from different directions, polarization is achieved in one direction, and wave shielding is achieved in the other direction.

Embodiment 3

[0048] On the basis of the above embodiment, the electromagnetic wave polarization control material is used to detect whether the incident wave is a polarized wave. When the incident wave is a polarized wave with the electric field direction along the slit, it can pass through the polarization control material, otherwise it cannot pass through.

Abstract

Electromagnetic wave polarization control material based on polymer material doping and its application. The electromagnetic wave polarization control material includes a main body. Gaps are formed between the particles, and the gaps are used for polarization regulation of electromagnetic waves. The invention utilizes the metal particles in the same direction in the main body to realize the metal slit on the macroscopic whole of the polarization control material, so as to achieve the polarization modulation of the incident electromagnetic wave. Compared with the traditional electromagnetic wave polarizer, there is no need to set complicated and fine Electromagnetic wave polarization modulation can be realized by using microstructures or metasurfaces, and rapid production can be realized by using additive manufacturing technology, which greatly simplifies the preparation process and significantly improves production efficiency.

Description

technical field [0001] The invention relates to an electromagnetic wave polarizer, in particular to an electromagnetic wave polarization control material doped with a polymer material and an application thereof, which is suitable for the polarization of electromagnetic waves, especially terahertz waves. Background technique [0002] The orientation and amplitude of the electric field strength of an electromagnetic wave changing with time are called polarization in optics. If this change has a definite law, the electromagnetic wave is called a polarized electromagnetic wave. [0003] The electromagnetic wave polarizer can realize the polarization control of the incident wave. In the prior art, patent CN102769191A discloses a metamaterial capable of realizing polarization conversion. The metamaterial includes a substrate and a plurality of artificial microstructures arranged on the substrate, and the artificial microstructures affect the plane electromagnetic wave propagating ...
