Description
[technical field]
The present invention relates to ultra field of materials, relate to the medium substrate of ultra material particularly.
[background technology]
Ultra material generally forms by a plurality of ultra material function plate stack or by other rule array combination; Ultra material function plate comprises medium substrate and the array a plurality of artificial micro-structural on medium substrate; The medium substrate of existing ultra material is the organic or inorganic substrate of homogeneous material, like FR4, TP1 or the like.The a plurality of artificial micro-structural of array on medium substrate has specific electromagnetic property; Can produce electromagnetic response to electric field or magnetic field; Structure and arrangement regulation through to artificial micro-structural carry out precise design and control; Can make ultra material demonstrate the electromagnetic property that various general material does not have, if can converge, disperse and deviation electromagnetic wave etc.Existing medium substrate is as the fixing base of artificial micro-structural, owing to have the dielectric constant and the magnetic permeability of homogeneous on the whole, so can not produce distinctive response to electric field or magnetic field, promptly as far as whole ultra material, medium substrate does not have the electromagnetism modulation function.
[summary of the invention]
Technical problem to be solved by this invention is: the medium substrate that overcomes existing ultra material lacks the shortcoming of function; Provide a kind of medium substrate to have the ultra material that heterogeneous material distributes; Through changing the local dielectric constant that the medium substrate local material changes ultra material, make the expansion that on function, is applied of ultra material.
The present invention realizes that the technical scheme that goal of the invention adopts is; A kind of ultra material with heterogeneous material distribution; The ultra material function plate that comprises a plurality of arrays; Said ultra material function plate comprises medium substrate and the array a plurality of artificial micro-structural on medium substrate, and said medium substrate is made up of the base board unit of a plurality of different materials.
Ultra material is as a kind of new material that electromagnetic wave is had specific response and modulating characteristic; Be to combine by a plurality of ultra material function plate arrays; The medium substrate at artificial micro-structural and place thereof can be regarded the basic structural unit of forming ultra material function plate as, and the character of ultra material function plate depends primarily on the electromagnetic property and the array rule of a plurality of basic structural units.The electromagnetic property of single basic structural unit is mainly determined by the effective dielectric constant and the equivalent permeability of this basic structural unit, and the effective dielectric constant of single basic structural unit and equivalent permeability are by the common decision of medium substrate institute at artificial micro-structural and place thereof.Existing design to ultra material function plate all is effective dielectric constant and the equivalent permeability that changes single basic structural unit through structure that changes artificial micro-structural or size; At last a plurality of basic structural units are arranged according to certain rules; Can make ultra material function plate form some specific electromagnetic property, as to electromagneticly converge, disperse, electromagnetism modulation functions such as deviation and translation.
The present invention is for expanding the function design of ultra material function plate, is made up of the base board unit of a plurality of different materials through medium substrate is designed to.In different base board units; Because material is different, its dielectric constant is also with difference, like this; For array for a plurality of basic structural units in certain base board unit; Its effective dielectric constant is also with difference, and promptly medium substrate demonstrates the non-uniform Distribution of dielectric constant on the whole, and then makes the expansion that on function, is applied of ultra material.
During practical implementation; The shape of said base board unit can design arbitrarily as required, decides to intend the target area shape that changes its dielectric constant, as embodiment; Can base board unit be designed to a plurality of back-shaped structures or cirque structure; After a plurality of back-shaped structures or cirque structure are formed medium substrate, because different base board units is a material different, so the dielectric constant of whole medium substrate is distribution heterogeneous.
As embodiment, the big I of dielectric constant of a plurality of back-shaped structures or cirque structure elementary cell increases by gradient or reduces, and also can be size and alternately distribute.
The present invention in the specific implementation; Need distribute according to the dielectric constant of whole medium substrate and select the material of different base materials as base board unit; Difference according to the dielectric constant size can be selected from various ceramic base materials, plastic resin base material or composite material base neatly, therefore has material selectivity widely.
The invention has the beneficial effects as follows; Through being designed to, medium substrate forms by the base board unit of a plurality of different materials; Make the dielectric constant of medium substrate be non-uniform Distribution; Can be on the whole the dielectric constant of medium substrate be carried out any design flexible through size, the shape of design base board unit and the rule of arranging, and then make ultra material have more rich functions application.

[embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
The structural representation of ultra material is referring to accompanying drawing 1; Comprise a plurality of range upon range of ultra material function plates 100; Ultra material function plate 100 comprises medium substrate 101 and the array a plurality of artificial micro-structural 102 on medium substrate; Artificial micro-structural 102 can be regarded a ultra material basic structural unit as with the medium substrate at its place, is similar to the lattice in the crystal.Accompanying drawing 1 is the local enlarged diagram of ultra material microstructure, and to be the basic structural unit of counting the order of magnitude by material molecule form according to the rule array of arranging of artificial design actual ultra material.The structure of the artificial micro-structural 102 in the accompanying drawing 1 is " worker " font structure, as embodiment, can also adopt the I-shaped derivative type.
The present invention adopts following examples to implement:
Embodiment 1
In the present embodiment; The size of the dielectric constant of back-shaped base board unit 103 is increased progressively to the center by the periphery; Can select suitable material from ceramic base material, plastic resin base material or composite material base neatly; Make different back-shaped base board units 103 adopt material different to arrange, distribute thereby make ultra material have dielectric constant heterogeneous on the whole according to the size of dielectric constant.
The size and the quantity that should be appreciated that back-shaped base board unit 103 in the present embodiment can design arbitrarily as required, to satisfy the electromagnetic property requirement of ultra material.And; The dielectric constant size of each back-shaped base board unit 103 increases progressively the special case of just giving an example for the ease of explanation the present invention by the periphery in the present embodiment to the center; During practical implementation; The rule of arranging of the dielectric constant size of each back-shaped base board unit 103 also needs to decide according to predetermined ultra material electromagnetic property; Main idea of the present invention also is to adopt material different for the electromagnetic property of ultra material a kind of design approach to be provided through each back-shaped base board unit 103, and makes up through the arrange design of rule of artificial micro-structural on this design approach and the ultra material function plate, to reach the purpose of the function design approach of expanding ultra material.
