Number.It is demonstrated experimentally that during electromagnetic wave dielectric material heterogeneous by refractive index, can be to the big direction deviation of refractive index.Relative
(1 is generally near in the case that magnetic conductivity is certain), refractive index is only relevant with dielectric constant, in the case where the first base material is selected,
Using only the arbitrary value of metamaterial unit refractive index being realized (in certain limit the first man-made microstructure of electric field response
It is interior), under the center of antenna frequency, using simulation software, such as CST, MATLAB, COMSOL, a certain spy is obtained by emulating
The dielectric constant of the man-made microstructure (metal micro structure of plane flakes as shown in Figure 5) of setting shape is with topology

It is shaped as the metal micro structure shown in Fig. 5)：
First stage：According to restrictive condition is developed, in the case where b values keep constant, a values are changed to most from minimum value
Big value, the metal micro structure in this evolution process are " ten " font when minimum value (a take except).In the present embodiment, a minimum
Value is 0.3mm (line width W), and a maximum is (CD-WL).Therefore, in the first phase, the topology of metal micro structure
Differentiation as shown in figure 8, i.e. from the length of side be W square JX1, be gradually evolved into maximum " ten " font topology JD1.

Value increases continuously maximum, and the metal micro structure in this evolution process is plane flakes.In the present embodiment, b minimum
Value is 0.3mm, and b maximum is (CD-WL-2W).Therefore, in second stage, the topology of metal micro structure is drilled
Become as shown in figure 9, being the topological shape for the plane flakes that maximum is gradually evolved into from " ten " font topology JD1 of maximum
Shape JD2, the topology JD2 of maximum plane flakes herein refer to, the first metal branch J1 and the second metal branch J2
Length b can not extend again, otherwise the first metal branch will intersect with the second metal branch.In second stage,
With the differentiation of the topology of metal micro structure, the refractive index of corresponding metamaterial unit continuously increases (respective antenna
One specific frequency).
If the variations in refractive index scope that metamaterial unit is obtained by above-mentioned differentiation meets design needs (i.e. this change model
Enclose and contain nmin-nmaxScope).If the variations in refractive index scope that above-mentioned differentiation obtains metamaterial unit is unsatisfactory for design need
Want, such as maximum is too small, then changes WL and W, emulate again, until obtaining the variations in refractive index scope of our needs.
