Embodiment Construction

[0026] The present invention relates to a negative magnetic permeability metamaterial, such as figure 2 , image 3 As shown, at least one material sheet 1 is included, and each material sheet 1 includes a substrate 2 and a plurality of artificial microstructures 3 attached on the surface of the substrate 2 . The base plate 2 is in the shape of a flat plate, or in the shape of a thin sheet bent into a ring, or in the shape of a grid composed of a plurality of strips interlocked at right angles. The substrate 2 is usually made of non-metallic materials such as polytetrafluoroethylene, epoxy resin, FR4, and ceramics.

[0027] The artificial microstructures 3 are periodically arranged on the surface of the substrate 2, for example, arranged in a rectangular array, that is, the rows are arranged in the x direction and the columns are arranged in the y direction perpendicular to the x direction, and the spacing between the rows and the columns are respectively Equal, even if the ...

Abstract

The invention relates to a negative magnetic conductivity metamaterial, comprising a base plate made of a nonmetal material and multiple artificial microstructures, the multiple artificial microstructures are attached on the base plate, are periodically arranged and are silk threads of conductive materials, each artificial microstructure comprises an opening ring and two bent lines, the two bent lines respectively extend towards the interior of the opening ring in a serpentine bending manner from the two end points of the opening ring, and the two bent lines are not mutually crossed and are not crossed with the opening ring. According to the negative magnetic conductivity metamaterial disclosed by the invention, the artificial microstructures can remarkably improve the absolute value of negative magnetic conductivity of metamaterial so as to strengthen a negative magnetic conductivity effect and to meet requirements of the negative magnetic conductivity under special conditions.

Description

technical field [0001] The invention relates to the field of metamaterials, more specifically, to a negative magnetic permeability metamaterial. Background technique [0002] At present, there have been a lot of research on magnetic permeability in the world. Positive magnetic permeability has been relatively mature, but the current society urgently needs negative magnetic permeability metamaterials, so it plays a great role because it has very special functions, such as quantum Polarization can polarize the incident wave, so it has a wide range of action. For example, in the field of medical imaging, it can enhance the imaging effect of electromagnetic waves. It is also very useful in lens research and has a good application prospect. Therefore, the negative permeance is one of the hot research topics at home and abroad. [0003] In engineering practice, the magnetic permeability usually refers to the relative magnetic permeability, which is the absolute magnetic permeabil...
