10 surpass sheet of material, 12,14 medium substrates, 16 structure sheafs, 18 artificial micro-structurals, 20 radomes, 30 electromagnetic wave emission source
Embodiment
As shown in Figure 1, be super material provided by the invention.Described super material comprises and one surpasses sheet of material 10, and described super sheet of material 10 comprises two medium substrates 12 that fit together, 14 and place between described two medium substrates 12,14 and by described two medium substrates 12,14 structure sheafs 16 that cover.In the present embodiment, described two medium substrates 12,14 are all made by polytetrafluoroethylene (F4B).In other embodiments, described two medium substrates 12,14 also can be made by other polymer, are perhaps made by ceramic material.
As shown in Figure 2, described structure sheaf 16 comprises a plurality of artificial micro-structurals 18.The plane with certain topology or stereochemical structure that each artificial micro-structural 18 normally is made of metal wire, wherein, the cross section of metal wire can be for flat or other arbitrary shapes, as cylindric.Artificial micro-structural 18 shown in Fig. 2 is the planar structures that are made of the metal wire with flat cross section, and be and periodically arrange, also namely, described artificial micro-structural 18 is periodically to be arranged between described two medium substrates 12,14, and is covered by described two medium substrates 12,14.Generally, we can be with two medium substrates 12 at each artificial micro-structural 18 and place thereof, 14 part people for being defined as a super material cell, and the physical dimension of described artificial micro-structural 18 should belong to the same order of magnitude with the physical dimension of described super material cell.
In order to reduce the reflection of electromagnetic wave when the described super material of incident, will allow described super sheet of material 10 impedance close to or equal the impedance of air.We know that formula of impedance is
Wherein, μ is that relative permeability, ε are relative dielectric constant.Generally, relative dielectric constant ε and the relative permeability μ of air all are slightly larger than 1, and usually being similar to value in the reality is 1, so can be got by above-mentioned formula of impedance, the impedance Z of air is approximately 1.And the relative permeability μ of general most of materials approximates 1, changes smallerly, nor changes easily, and relative dielectric constant ε then can change easily.Therefore, for described super sheet of material 10, because the convertibility of each super material cell, we can regulate the relative dielectric constant ε of each super material cell with the resonant ring of opening, so that the relative dielectric constant ε of each super material cell of described super sheet of material 10 is as far as possible little, preferably close to 1.In the present embodiment, the triangular ring structure that described artificial micro-structural 18 is openings, as shown in Figure 3.
Please refer to Fig. 3, described triangular ring structure is surrounded by three metal line and forms, and offers an opening on the one metal wire; Described opening is opened in the middle part of described metal wire, and over against an angle of described triangular ring structure.In the present embodiment, described metal wire is copper cash.
Make the relative dielectric constant ε of each super material cell of described super sheet of material 10 as far as possible little, we can be earlier in the physical dimension of computer analog software triangular ring structure as described in the electromagnetic wavelength of response is constantly regulated as required on as CST, as the width of each metal line and length size etc., minimum and close to 1 physical dimension until the relative dielectric constant ε that obtains to make each super material cell.Accordingly, can make impedance close to or equal the described super sheet of material 10 of the impedance of air, allow the impedance of described super material and the impedance phase of air mate, also form " solid-state air ", reflection was little when not only electromagnetic wave was from the described super material of air incident, and because electromagnetic wave is propagated in described super material as propagation in air, loss is little, efficiency of transmission is high, therefore, saturating ripple rate height.
In addition, described super material also can be formed by stacking by the described super sheet of material 10 of multilayer.
Please refer to Fig. 4, for radome 20 of the present invention, for the protection of antenna, as the electromagnetic wave emission source 30 among the figure.Described radome 20 is made by super material of the present invention, because described artificial micro-structural 18 is protected by described medium substrate 12,14, difficult drop-off and wearing and tearing like this, can keep stable electromagnetic performance.Radome 20 in the present embodiment is curved shape, and it forms by the plate super sheet of material 10 of hot pressing.In other embodiments, also can use soft medium substrate to make flexible super sheet of material 10, perhaps the plate super sheet of material 10 of polylith is stitched together, and the radome 20 of formation different shape.
In addition, according to the situation of described radome 20 needs load-bearing, the super sheet of material 10 of multi-disc can be superimposed to increase the thickness of described radome 20, so not only can not cause electromagnetic loss, and can strengthen the mechanical strength of described radome 20, make it more sturdy and durable.
The above only is some embodiments of the present invention and/or embodiment, should not be construed as limiting the invention.For those skilled in the art, under the prerequisite that does not break away from basic thought of the present invention, can also make some improvements and modifications, and these improvements and modifications also should be considered as protection scope of the present invention.
