Embodiment Construction

[0021] This embodiment provides a broadband artificial electromagnetic material, its structure is as follows figure 1 As shown, at least one sheet of material is included, and when there are multiple sheets of material, the sheets of material are stacked together in a direction perpendicular to their surfaces.

[0022] As shown in Figure 1, the material includes three material sheets 1 of uniform thickness, and multiple material sheets 1 are stacked in sequence along the direction (z-axis direction) perpendicular to the plane of the substrate. Through a certain packaging process such as welding, riveting, bonding, etc., it becomes a whole, or it is filled with a substance that can connect the two, such as a liquid substrate material, which bonds the existing two material sheets 1 after curing, so that multiple The block material sheet 1 constitutes a whole.

[0023] Each material sheet 1 includes a substrate and an artificial microstructure attached to the substrate, which vi...

Abstract

Provided in the present invention is an artificial microstructure comprising a snap ring structure and an H-shaped structure partially embedded within the snap ring structure. Also provided in the present invention is an artificial electromagnetic material comprising the artificial microstructure. The artificial electromagnetic material having the structure is provided, in a broad range of frequency bands, with great refractive index and smooth changes, and with a dielectric constant that gradually increases from zero within a certain frequency band, thus meeting requirements of particular scenarios, such as the fields of semiconductor manufacturing and antenna manufacturing, and having broad application prospects.

Description

technical field [0001] The invention relates to an artificial electromagnetic material, more specifically, to a broadband artificial electromagnetic material. Background technique [0002] Artificial electromagnetic material, commonly known as metamaterial, is a new type of artificial synthetic material that can respond to electromagnetic waves. It consists of a substrate and an artificial microstructure attached to the substrate. The artificial microstructure is a planar or three-dimensional structure composed of metal wires with a certain geometric pattern, such as circular rings, I-shaped metal wires, etc. The artificial electromagnetic material can respond to electromagnetic waves, so that the artificial electromagnetic material as a whole reflects the electromagnetic characteristics different from the substrate, such as the dielectric constant ε and magnetic permeability μ are different, according to the refractive index formula It can be seen that the refractive inde...
