Embodiment Construction

[0042] 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.

[0043] The metamaterial according to the present invention includes one or more metamaterial sheets, the metamaterial sheets include a substrate and a plurality of metal microstructures attached to the substrate, and the substrate is an organic substrate without reinforcing materials.

[0044] Using the principle that metamaterials can modulate electromagnetic waves, various types of metamaterials can be designed. Metamaterials can be divided into functional metamaterials and metamaterial antennas according to whether the refractive index distribution inside the metamaterials is uniform.

Abstract

The invention provides a metamaterial which comprises one or more metamaterial sheet layers. Each metamaterial sheet layer comprises a base board and a plurality of metal microstructues adhered onto the base board, wherein the base board is an organic base board without reinforcement materials. The invention further relates to a preparation method of the metamaterial. The metamaterial is prepared by adhering the metal microstructues onto the base boards, so that incident electromagnetic waves can be modulated in various aspects, such as converging the electromagnetic waves, absorbing the electromagnetic waves, modulating transparency, high dielectric constant, high permeability and negative permeability of the electromagnetic waves, and the like. Besides, due to the base boards are low-loss organic base boards without reinforcement materials, loss and dielectric constant of the metamaterial are reduced, and light application of the metamaterial is facilitated.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a metamaterial based on an organic resin substrate without reinforcing materials and a preparation method thereof. 【Background technique】 [0002] Light, as a kind of electromagnetic wave, when it passes through glass, because the wavelength of light is much larger than the size of atoms, we can use the overall parameters of the glass, such as the refractive index, rather than the detailed parameters of the atoms that make up the glass to describe The response of glass to light. Correspondingly, when studying the response of materials to other electromagnetic waves, the response of any structure in the material whose scale is much smaller than the wavelength of the electromagnetic wave to electromagnetic waves can also be described by the overall parameters of the material, such as the dielectric constant ε and magnetic permeability μ. By designing the structure of each point of t...
