Abstract
The invention relates to a metamaterial which is formed by stacking at least one metamaterial slice layer. Each metamaterial slice layer comprises a substrate and a plurality of artificial microstructures attached onto the substrate; and the substrate is a flexible insulating substrate. The substrate adopts the flexible insulating substrate, so the metamaterial is soft and can be bent, and thus, the application range of the metamaterial is expanded.
Description
Technical field
The present invention relates to field of new, more particularly, relate to a kind of novel ultra material.
Background technology
Ultra material is a kind of artificial composite structure material with the not available extraordinary physical property of natural material, through the orderly arrangement to micro-structural, can change relative dielectric constant and magnetic permeability in the space at every.Therefore ultra material can be realized dielectric constant and the magnetic permeability that common material can't possess within the specific limits, thereby can effectively control the electromagnetic wave propagation characteristic.
Usually use material such as FR-4 in the existing ultra material design as substrate.The common thermal property of this type material, pliability and reliability are relatively poor.
Flexible PCB is widely used in fields such as computer peripheral equipment, space flight and aviation, communication and LCD at present, but also is not used to ultra field of materials.
Summary of the invention
The technical problem that the present invention will solve is, to the defective of prior art, a kind of better flexible ultra material that has is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ultra material; Pile up by the ultra sheet of material of a slice at least and to form; Each ultra sheet of material comprises substrate and attached to a plurality of artificial micro-structural on the said substrate, said substrate is the flexible insulation substrate.
In preferred implementation of the present invention, said flexible insulation substrate is a polyimides.
In preferred implementation of the present invention, said flexible insulation substrate is a PETG.
In preferred implementation of the present invention, said flexible insulation substrate is the aramid fiber ester.
In preferred implementation of the present invention, said flexible insulation substrate is a polyvinyl chloride.
In preferred implementation of the present invention, said artificial micro-structural through etching, plating, brill quarter, photoetching, electronics is carved or ion is carved and is attached on the said substrate.
In preferred implementation of the present invention, be of similar shape attached to the artificial micro-structural on the substrate.
In preferred implementation of the present invention, said artificial micro-structural is " I " shape.
In preferred implementation of the present invention, said artificial micro-structural is " ten " shape.
In preferred implementation of the present invention, said artificial micro-structural is a snowflake shape.
Embodiment of the present invention has following beneficial effect: because substrate adopts the flexible insulation substrate, can bending so ultra material is soft, and then expanded the scope of application of ultra material.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of artificial micro-structural for the ultra material of " I " shape;
Fig. 2 is the structural representation of artificial micro-structural for the ultra material cell of " ten " shape;
Fig. 3 is that artificial micro-structural is the structural representation of the ultra material cell of snowflake shape
Embodiment
As shown in Figure 1, ultra material comprises that 1,3 ultra sheet of material 1 of 3 ultra sheet of material stacks gradually along the z direction of principal axis, and is bonding through adhesive between the different lamellas, thereby makes the ultra sheet of material 1 of multi-disc be stacked into an integral body.Each ultra sheet of material comprises the flexible insulation substrate and attached to the artificial micro-structural of " I " shape on the flexible insulation substrate.
The flexible insulation substrate is a polyimides, also can be PETG, aramid fiber ester or polyvinyl chloride; The artificial micro-structural of " I " shape through etched mode attached on the flexible insulation substrate, also can through electroplate, bore quarter, photoetching, electronics is carved or ion quarter etc. mode be attached on the flexible insulation substrate.
The ultra material substrate of flexibility on each ultra sheet of material 1 is divided into a plurality of identical cube base board units that are close to each other virtually, and these base board units are row, are leu time array arrangement with vertical with it y direction of principal axis with the x direction of principal axis.The length of side of base board unit be generally the incident electromagnetic wave wavelength 1/5th to 1/10th between.Be attached with an artificial micro-structural 2 of " I " shape on each base board unit; Ultra material cell 3 of artificial micro-structural 2 common formations on base board unit and the base board unit; As shown in Figure 1, ultra material of the present invention can be regarded as by a plurality of ultra material cell 3 and forms along x, y, three direction array arrangements of z.
Ultra material cell 3 can also be as shown in Figures 2 and 3, and the artificial micro-structural in the ultra material cell shown in Figure 2 is " ten " shape, and the artificial micro-structural in the ultra material cell shown in Figure 3 is a snowflake shape.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of distortion, can comprise that such as ultra material a ultra sheet of material also can comprise a plurality of ultra sheet of material; Artificial micro-structural can also be other shapes, such as circular, ellipse, triangle or irregular shape etc.These all belong within the protection of the present invention.
