Embodiment
Light, as electromagnetic a kind of, it is when passing glass, because the wavelength of light is much larger than the size of atom, therefore we can use the univers parameter of glass, and the details parameter of the atom of for example refractive index, rather than composition glass is described glass to the response of light.Accordingly, when research material is to visible light or other electromagnetic responses, any yardstick also can be used the univers parameter of material in the 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. described.The structure by every of designing material is so that thereby the specific inductive capacity of material each point and magnetic permeability are all identical or different so that the specific inductive capacity of material monolithic and magnetic permeability are certain rule arranges, the magnetic permeability that rule is arranged and specific inductive capacity can be so that material have response on the macroscopic view to electromagnetic wave, such as converging 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 of the elementary cell of the super material of formation.The elementary cell of super material comprises the base material 2 that artificial microstructure 1 and this artificial microstructure are adhered to.Among 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 on each super material elementary cell can change each super material elementary cell to the response of incident electromagnetic wave.A plurality of super material elementary cells are arranged according to certain rules can be so that super material has the response of macroscopic view to electromagnetic wave.Because super material monolithic needs have macroscopical electromagnetic response so each super material elementary cell need form continuous response to the response of incident electromagnetic wave to 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 when visible light-responded, then the size of each super material elementary cell should be nanoscale on the super material.During this section is described, the material monolithic that will surpass that we are artificial is divided into a plurality of super material elementary cells, but should know that this kind division methods only for convenience of description, should not regard super material as by a plurality of super material elementary cells splicings or assemble, super material is that artificial metal's microstructure cycle is arranged on the base material and can consists of in the practical application, and technique is simple and with low cost.Cycle arranges and refers to that namely the artificial metal's microstructure on above-mentioned our artificial each super material elementary cell of dividing can produce continuous electromagnetic response to incident electromagnetic wave.
