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 the response of glass to light.Accordingly, when research material was to other electromagnetic responses, any yardstick also can be represented with the univers parameter of material electromagnetic response much smaller than the structure of electromagnetic wavelength in the material, for example describes with DIELECTRIC CONSTANTS and magnetic permeability μ.Thereby the structure through every of designing material makes all identical with magnetic permeability or different dielectric constant that makes material monolithic of the dielectric constant of material each point and magnetic permeability be certain rule and arranges; Magnetic permeability that rule is arranged and dielectric constant can make material that electromagnetic wave is had the response on the macroscopic view, for example converge electromagnetic wave, divergent electromagnetic ripple, absorb electromagnetic wave etc.Such have magnetic permeability that rule arranges and dielectric constant material we be referred to as ultra material.
As shown in Figure 1, Fig. 1 is the perspective view of the elementary cell of the ultra material of formation.The elementary cell of ultra material comprises the base material 1 that artificial micro-structural 2 and this artificial micro-structural are adhered to.Among the present invention; Artificial micro-structural 2 is artificial metal micro structure; Artificial metal's micro-structural has and can produce the 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 micro-structural on each ultra material elementary cell can change the response of each ultra material elementary cell to incident electromagnetic wave.In one embodiment of the invention, also be coated with cover layer 3 on the artificial micro-structural 2, cover layer 3, artificial micro-structural 2 and base material 1 constitute the elementary cell of the ultra material of the present invention.A plurality of ultra material elementary cells are arranged according to certain rules and can be made ultra material electromagnetic wave had the response of macroscopic view.Because ultra material monolithic needs have macroscopical electromagnetic response so each ultra material elementary cell need form continuous response to the response of incident electromagnetic wave to incident electromagnetic wave; This size that requires each ultra material elementary cell is preferably 1/10th of incident electromagnetic wave wavelength less than 1/5th of incident electromagnetic wave wavelength.During this section is described; The material monolithic that will surpass that we are artificial is divided into a plurality of ultra material elementary cells; But it is convenient to know that this kind division methods is merely description; Should not regard ultra material as by a plurality of ultra material elementary cells splicings or assemble, ultra material is that artificial metal's micro-structural cycle is arranged on the base material and can constitutes in the practical application, and technology is simple and with low cost.Cycle arranges and refers to that promptly the artificial metal's micro-structural on above-mentioned our artificial each ultra material elementary cell of dividing can produce continuous electromagnetic response to incident electromagnetic wave.
When only on base material the cycle arrange single artificial metal's micro-structural reaching when absorbing electromagnetic effect because the limitation of single artificial metal's micro-structural, it only can realize absorbing electromagnetic performance usually on a frequency or narrower frequency range.Yet when practical application, need still can reach in the frequency range of broad usually and absorb electromagnetic effect.
