[background technology]
Meta Materials refers to some artificial composite structures with the extraordinary physical property not available for natural material or composite material; By the structurally ordered design on the key physical yardstick of material, the restriction of some apparent natural law can be broken through, thus obtain the meta-materials function exceeding the intrinsic common character of nature.
Meta Materials is made up of medium substrate and the multiple man-made microstructure be arranged on substrate, can provide the material behavior that various common material has and do not have.Single man-made microstructure size is generally less than 1/10 wavelength, and it has electroresponse and/or magnetic response to extra electric field and/or magnetic field, thus has and show effective dielectric constant and/or equivalent permeability.The effective dielectric constant of man-made microstructure and equivalent permeability are determined by its topological structure and physical dimension parameter, can artificially design and control.Further, man-made microstructure can have the anisotropic electromagnetic parameter of artificial design.
Dielectric constant is the significant data characterizing dielectric or insulating material electrical property, and conventional ε represents.It refer in same capacitor with same substance be dielectric and vacuum time the ratio of electric capacity, represent that dielectric stores the relative ability of electrostatic energy in the electric field.Dielectric constant has plural form, real part is called dielectric constant, imaginary part is called fissipation factor, the usual coupling ability representing material and microwave by the loss tangent value ratio of dielectric constant (fissipation factor with), loss tangent value is larger, and the coupling ability of material and microwave is stronger.If there is the material of high-k to put in the electric field, the intensity of electric field can have objective decline in dielectric, and in high dielectric constant material, electromagnetic wavelength is very short, greatly can reduce the size of radio frequency and microwave device, the dielectric constant of existing material is all lower.
Usually " work " font man-made microstructure is as shown in Figure 1 adopted to go the dielectric constant distribution changed in space in existing Meta Materials design production technology, " work " font man-made microstructure comprises horizontal line 11, lower horizontal line 12 and vertical line 13, adopting work " font man-made microstructure goes the dielectric constant distribution changed in space to be usually difficult to ensure that variations in refractive index is less on a band frequency namely have larger refractive index at wide frequency ranges in dispersionless situation.The material of ultra-high dielectric coefficient is not almost had in prior art.
