Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The metamaterial of the present invention consists of at least one such as figure 1 The metamaterial sheets 10 shown are stacked to form, as figure 1 and figure 2 As shown, each metamaterial sheet 10 includes a substrate 11, an empty plate 13, and a plurality of artificial microstructures 12 arranged periodically between the substrate 11 and the empty plate 13, and the empty plate 13 is provided with periodic arrays. There are a plurality of circular holes in the cloth, and micropores smaller than the circular holes are also arranged in the gaps between every four circular holes. Prefera...

Abstract

The invention provides a metamaterial which is formed by at least one metamaterial piece layer in an overlapped mode. Each metamaterial piece layer comprises a substrate, a bare board and a plurality of man-made micro-structures which are cyclically arranged between the substrate and the bare board. A plurality of cyclically-distributed circular holes are formed in each bare board. Micro holes which are smaller than the circular holes are further formed in gaps among the four circular holes. According to the metamaterial, due to the facts that the circular holes are formed and the micro hole smaller than the circular holes are formed in the gaps among the four circular holes, a dielectric constant and dielectric loss of the bare board are reduced, a pore rate of the bare board can be controlled by controlling the shapes and the arrangements of the circular holes and the micro holes, therefore, the substrate with the wanted dielectric constant is obtained, and the dielectric constant of the metamaterial piece layers is controlled so as to obtain the metamaterial piece layers with the small dielectric constant and small dielectric loss.

Description

technical field [0001] The invention belongs to the field of artificial composite materials, in particular to a supermaterial. Background technique [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, it is possible to break through the limitations of some apparent natural laws, so as to achieve supernormal material functions beyond the ordinary properties inherent in nature. A metamaterial usually includes a substrate and a plurality of artificial microstructures periodically arranged on the substrate. Each artificial microstructure and the part of the substrate to which it is attached can be regarded as a metamaterial unit. The properties and functions of metamaterials are jointly determined by the characteristics of the substrate and the characteristics of the artificial mi...
