Embodiment Construction

[0026] The present invention relates to a metamaterial with negative magnetic permeability, such as figure 2 , image 3 As shown, at least one material sheet layer 1 is included, and each material sheet layer 1 includes a substrate 2 and a plurality of artificial microstructures 3 attached on the surface of the substrate 2. The substrate 2 is in the shape of a flat plate, and may also be in the shape of a sheet bent into a ring, or a grid formed by orthogonally buckling a plurality of long plates. The substrate 2 usually selects 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, such as a rectangular array arrangement, that is, arranged in an x ​​direction as a row and a y direction perpendicular to the x direction as a column, and the row spacing and column spacing are respectively Equal, even the row spacing is equal to the column spacing....

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 present invention relates to the field of metamaterials, and more specifically, to a metamaterial with negative permeability. Background technique [0002] At present, there has been a lot of research on magnetic permeability in the world, and the positive permeability has been relatively mature, but the society urgently needs the negative permeability metamaterial, so it has a great effect because it has a very special function and has quantum Polarization can polarize the incident wave, so it has a wide range of effects. 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 good application prospects. Therefore, the negative permeance is one of the current research hotspots at home and abroad. [0003] In engineering practice, magnetic permeability usually refers to the relative permeability, which is the absolute permeability μ and the magnetic constant...
