Problems solved by technology

A large part of the response ability of existing metamaterials to electromagnetic waves is determined by the microstructure. However, when metamaterials need to respond to electromagnetic waves with a large span of certain electromagnetic parameters to achieve specific functions, for example, for incident angles from 0 to 90° When all electromagnetic waves have a wave-transmitting effect, or polarization conversion can be realized for electromagnetic waves with a polarization angle of 0 to 90°, if the conventional metamaterial design method is used at this time, such as simulating a certain microstructure and changing its topology or size, etc. to obtain metamaterials that meet the needs becomes quite difficult, or even impossible, because there are limits to the ability of microstructures to respond to electromagnetic waves

Embodiment Construction

[0064] Please refer to figure 1 , figure 1 It is a schematic diagram of a three-dimensional structure in a preferred embodiment of the metamaterial of the present invention. figure 1 Among them, the metamaterial includes a substrate 10 and a plurality of artificial microstructures 11 arranged on the surface of the substrate 10. The metamaterial includes multiple electromagnetic regions D1, D2, D3, D4, and D5. figure 1 In the electromagnetic region D1, a plurality of artificial microstructures 11 are arranged, and other electromagnetic regions are filled with different filling patterns to show distinction. However, it can be seen that there are also a plurality of artificial microstructures in other electromagnetic regions. Each electromagnetic area corresponds to one or more electromagnetic parameter ranges of electromagnetic waves incident into the electromagnetic area.

[0065] figure 1 In this case, the surface of the substrate 10 is flat. The method for providing artificial m...

Abstract

The invention discloses a metamaterial. The metamaterial comprises at least one layer of base materials, a plurality of manual micro-structures which are arranged on surfaces of layers of base materials and a plurality of electromagnetic regions, wherein the electromagnetic wave entering all electromagnetic regions is provided with one or more electromagnetic parameter ranges, manual micro-structures in all electromagnetic regions generate electromagnetic response for the electromagnetic wave entering the electromagnetic regions. The metamaterial is divided into a plurality of electromagnetic regions, manual micro-structures in all electromagnetic regions respond to the electromagnetic wave in electromagnetic parameter ranges, the metamaterial design is simplified and the application range of the metamaterial can be enlarged.

Description

Technical field [0001] The technical field of metamaterials of the present invention particularly relates to a metamaterial and a metamaterial design method. Background technique [0002] Metamaterials are a new type of artificial material that has been developed in the past ten years to modulate electromagnetic waves. The basic principle is to artificially design the microstructure of the material (or artificial "atom"), so that such microstructure has specific electromagnetic properties. Therefore, a material composed of a large number of microstructures can have the electromagnetic function needed by people in a macroscopic view. Unlike traditional material technology that develops electromagnetic utilization methods based on the natural properties of existing materials in nature, metamaterial technology is to artificially design the properties of materials and manufacture materials according to needs. Metamaterials are generally composed of a certain number of artificial mic...
