Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
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 used the univers parameter of material much smaller than the structure of electromagnetic wavelength to electromagnetic response in the material, and for example DIELECTRIC CONSTANTS and magnetic permeability μ describe.Structure through every of designing material makes the dielectric constant of material each point all identical or different with magnetic permeability; Thereby making dielectric constant and the magnetic permeability of material monolithic be certain rule 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 has magnetic permeability that rule arranges and the material of dielectric constant is 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 2 that artificial micro-structural 1 and this artificial micro-structural are adhered to.Artificial micro-structural can be artificial metal's micro-structural; It has plane or three-dimensional topological structure to incident electromagnetic wave electric field and/or magnetic field generation response; Change the pattern and/or the size of the artificial metal's micro-structural on each ultra material elementary cell, can change of the response of each ultra material elementary cell incident electromagnetic wave.A plurality of ultra material elementary cells are arranged according to certain rules, can make ultra material electromagnetic wave had the response of macroscopic view.Because ultra material monolithic needs that incident electromagnetic wave is had macroscopical electromagnetic response; Therefore each ultra material elementary cell need form continuous response to the response of incident electromagnetic wave; This size that requires each ultra material elementary cell is preferably incident electromagnetic wave 1/10th wavelength less than incident electromagnetic wave 1/5th wavelength.During this section is described; To surpass material monolithic, to be divided into a plurality of ultra material elementary cells are a kind of man-made division methods; But it is convenient to know that this kind division methods is merely description; Ultra material both can or assemble by a plurality of ultra material elementary cell splicings, also can artificial metal's micro-structural cycle be arranged on the base material to constitute, and technology is simple and with low cost.Artificial metal's micro-structural that cycle arranges on each the ultra material elementary cell that promptly refers to above-mentioned artificial division can produce continuous electromagnetic response to incident electromagnetic wave.
The present invention utilizes arrange metal patch and a substrate surface of above-mentioned ultra material principle cycle between two blocks of base materials to attach the resistance screen to form the salisbury screen, combines salisbury to shield and surpasses material to reach the wideband wave-absorbing effect.
