Embodiment
Light, as electromagnetic one, it is in passing glass, because the wavelength of light is much larger than the size of atom, therefore we can use the univers parameter of glass, for example refractive index, instead of the details parameter of the atom of composition glass is described the response of glass to light.Accordingly, when research material is to visible ray or other electromagnetic responses, in material, any yardstick also can be used the univers parameter of material to electromagnetic response much smaller than the structure of electromagnetic wavelength, and such as DIELECTRIC CONSTANT ε, magnetic permeability μ, refractive index, impedance etc. are described.All thereby the identical or different specific inductive capacity that makes material monolithic and magnetic permeability are certain rule and arrange to make the specific inductive capacity of material each point and magnetic permeability by the structure of every of designing material, the magnetic permeability that rule is arranged and specific inductive capacity can make material have the response in macroscopic view to electromagnetic wave, for example, converge electromagnetic wave, divergent electromagnetic ripple etc.Such have magnetic permeability that rule arranges and specific inductive capacity material we be referred to as super material.
As shown in Figure 2, Fig. 2 is the perspective view that forms the elementary cell of super material.The elementary cell of super material comprises the base material 2 that artificial microstructure 1 and this artificial microstructure are adhered to.In the present invention, artificial microstructure is artificial metal micro structure, artificial metal's microstructure has and can produce plane or the three-dimensional topological structure of response to incident electromagnetic wave electric field and/or magnetic field, and the pattern and/or the size that change the artificial metal's microstructure in each super material elementary cell can change the response of each super material elementary cell to incident electromagnetic wave.Multiple super material elementary cells are arranged according to certain rules and can be made super material have macroscopical response to electromagnetic wave.Due to super material monolithic need to incident electromagnetic wave have macroscopical electromagnetic response therefore each super material elementary cell need form continuous response to the response of incident electromagnetic wave, this requires each super material elementary cell to be of a size of 1/10th to 1/5th of incident electromagnetic wave wavelength, is preferably 1/10th of incident electromagnetic wave wavelength.When super material require is when visible light-responded, on super material, the size of each super material elementary cell should be nanoscale.During this section is described, what we were artificial will surpass material monolithic is divided into multiple super material elementary cells, but should know that this kind of division methods only for convenience of description, should not regard super material as by multiple super material elementary cell splicings or assemble, in practical application, super material is that artificial metal's microstructure cycle is arranged on base material and can be formed, and technique is simple and with low cost.Cycle arranges and refers to that the artificial metal's microstructure in above-mentioned our artificial each super material elementary cell of dividing can produce continuous electromagnetic response to incident electromagnetic wave.
As shown in Figure 3, Figure 4, Fig. 3, Fig. 4 are respectively the positive view and the sectional view that utilize the spectacles eyeglass of the present invention that above-mentioned super material principle makes.In Fig. 3, Fig. 4, spectacles eyeglass entirety of the present invention is tabular, and unconventional concavees lens shape.The first matching layer 11 and the second matching layer 12, two matching layers that spectacles eyeglass of the present invention comprises functional layer 10 and is symmetricly set in functional layer both sides all have thickness L, and whole spectacles eyeglass has thickness d, and functional layer has thickness d-2L.In the positive view of spectacles eyeglass of the present invention, the spectacles eyeglass initial stage is shaped as the circle that a radius is R, and in the time of post-production, cutting this radius according to the shape of picture frame is that the circular eyeglass of R can obtain final eyeglass.On the circular eyeglass that is R at this radius, center of circle O is center of lens point and is wearing the pupil of Shi Yingzheng to patient.Known in conjunction with sectional view, the circular eyeglass that spectacles eyeglass essence is R by three radiuses is formed by stacking, and comprises the first matching layer 11, the second matching layer 12 and is positioned at the first matching layer 11 and the middle functional layer 10 of the second matching layer 12.In functional layer, taking O point as the center of circle, the refractive index at same radius place is identical, and the index distribution of whole functional layer can be rotated a circle and obtain around its central axis by side section.Index distribution in index distribution and the functional layer of the first matching layer and the second matching layer and its thickness relationship are related.Therefore determining after the index distribution of side section, can obtain the index distribution of whole eyeglass.
As shown in Figure 5, Fig. 5 is that spectacles eyeglass sectional view index distribution of the present invention is calculated with reference to figure.The index distribution of spectacles eyeglass of the present invention is the response to optics with reference to concavees lens.Concavees lens have uniform refractive index but have inhomogeneous thickness, and spectacles eyeglass of the present invention has uniform thickness, so must have inhomogeneous index distribution.When patient demand refractive index is n
0common concave spectacle lens time, according to well known to a person skilled in the art optical theory, can extrapolate the thickness D of this common concavees lens center
min, the thickness D of edge
max, be D (h) apart from the thickness at common concavees lens central point h place.Corresponding h height, the refractive index of spectacles lens function layer of the present invention is n (h).Both sides matching layer is the reflection in order to reduce light, therefore needs to make refractive index by the minimum refractive index n in functional layer
mintaper to the refractive index n (h) that is in contact with it functional layer, the refractive index of both sides matching layer outside surface is n
min, the refractive index of inside surface is n (h), on spectacles eyeglass side section of the present invention, index distribution schematic diagram is as shown in Figure 6.
In the present invention, the integral thickness d of spectacles eyeglass can obtain according to relational expression below:
The thickness L of matching layer is:
In functional layer, the refractive index n (h) of central shaft h At The Height is:
The refractive index of monosymmetric the first matching layer of functional layer and the second matching layer is to be linear distribution along with the variation in thickness of this layer, as shown in Figure 6, x axle represents the variation of spectacles lens thickness, and within the scope of 0≤x≤L, on the first matching layer, variations in refractive index rule is:
Within the scope of d-L≤x≤d, on the second matching layer, variations in refractive index rule is:
Known according to super material principle, change the size of the artificial microstructure of each super material cell and/or pattern and can change specific inductive capacity and the magnetic permeability value of each super material cell, also change the refractive index value of each super material cell.The artificial microstructure that can reach above-mentioned index distribution has multiple, introduces two kinds of more conventional structures below.
