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

The invention relates to a broadband artificial electromagnetic material, which comprises at least one base material and artificial micro structures attached to the base materials, wherein each artificial micro structure comprises an opening annular structure and an I-shaped structure partially embedded into the opening annular structure. By the artificial electromagnetic material with the structure, the refractive index is relatively large in a relatively wide frequency band range and is changed steadily; furthermore, the dielectric constant is gradually increased from zero within a certain frequency band; a requirement of a special occasion can be met, in particular the fields of semiconductor manufacturing, antenna manufacturing and the like; and the broadband artificial electromagnetic material has a wide application prospect.

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...
