Specific implementing manner

[0024] this invention claims a multiple resonance ultrasonic material includes at least one *** non-conductive material which is made of the base plate and attached on the surface of base plate the plurality of same and periodically arranged artificial micro structure. The manufacturing of the base plate a conductive material has many choices such as ceramic fr4 f4b polyfluortetraethylene *** or hdpe high density a high density polyethylene abs *** an acrylonitrile butadiene styrene ferroelectric material or iron magnetic material and so on.

[0025] i is not shown as picture the embodiment in the resonance ultrasonic material i has two layers of the base plate 2 two base plates 2 between the contact surface of the upper attached with the artificial micro structure 3. Artificial micro structure 3 is made from conducting material of the lead wire with certain geometry of the pattern plane structure. The conductive material may be golden silver copper and so on good conductivity of metal material or the main component is in golden silver copper *** or two of the alloy material can also be carbon nanometre tube doped with aluminium zinc oxide indium tin oxide and so on can be conductive of non-metal material. In the invention preferably copper or silver.

[0026] artificial micro structure with 3 body geometric pattern the shape of the picture as picture 2 1 3 represented it is composed of herringbone line 30 and the /\ shaped frame line 31. Said lambdoidal frame line 31 is around the herringbone line 30 the outer edge of *** ring are encircled to form the closed curve of the lambdoidal frame line 31 of the inner contour that is formed by personal *** shape preferably herringbone line 31 frame with the inner outline and the corresponding lambdoidal line 30 the outer edge of the distance between the processing process is equal to that of the lambdoidal frame the line width of line 31 is constant.

[0027] *** the ground step 3 if the image drawing 4 the herringbone line 30 comprises three are the same and the end point of the electrode wire 300 three electrode line 300 two are the 120 degree so as to make the herringbone line 300 to the end point as rotary centre randomly rotating and 120 degrees based on original structure is superposed with the end point to be herringbone line 30 the central point of the o.

[0028] is like herringbone line 31 frame also comprises three same * shaped opening *** 310 frame each of the 310 *** frame comprises two parallel and equal to the parallel line and connected with two parallel line the end part of the vertical to the parallel line connecting line of the two parallel thread is located on connecting line of the same side of the. *** 310 each of the frame around the a electrode line 300 outer part of the electrode wire 300 parallel to the frame *** 310 of the parallel line and plane is divided into two parallel line distance. Picture 3 represented the frame three *** 310 head-to-tail *** are connected and form a closing frame line and any one of the frame around *** 310 herringbone line 30 the central point of the o rotating 120 degrees the adjacent the open frame *** overlapping namely the lambdoidal frame by the central line 31 point o the rotation of 120 degrees is connected with the original structure is overlapped with.

[0029] artificial micro structure 3 periodically arranged on base plate 2 way is arranged with a common such as rectangular array is distributed to any direction it is vertical to the direction is the direction sequence according to certain spacing and row spacing can be arranged.

[0030] in this invention according to human manufacturing microstructure 3 the structure point is designed *** new of the seasonal arrangement mode of the display picture 5 with the central *** personal manufacturing microstructure 3 one of electrode wire 300 the direction of the time of the x direction with the electrode wire 300*60 of 60 degree in clockwise or anticlockwise direction it is able to be 60 degrees is the direction y direction and arranged as array arranging and the distance between the same row the adjacent two artificial micro structure 3 the center point of the o o2 the distance between the equal to z recording the sequence the distance between the same row the adjacent two artificial micro structure 3 the centre point of cko1 the distance between the a to z. Is 5 can be known it is comprised of an adjacent two rows adjacent two rows of the four artificial micro structure the central point of the kopc ^ o3 four points of the connecting wire of an acute angle is 60 of the rhombic quadrangle. By using this method can be arranged as far as possible it fully makes use of the surface of the base plate 2 space by arranging the angle of the artificial micro structure 3. So the spacing and row distance between the electrode wire the length of one time at least two times when the said four artificial micro structure between not containing the personal *** manufacturing micro structure is arranged at the same time the tightness of the best substrate surface area using the full.

[0031] using the similar to the third electrode the artificial micro structure can make the material has multiple resonance frequencies so it can be used for the frequency is equal to the resonance frequency of the specific electromagnetic wave energy consumption and the filter and the other frequency electromagnetic wave can be high efficiency through. According to the needed electromagnetic wave of the resonant frequency of the size can be applied to regulate artificial micro structure 3 the size and the distance between the line it can meet different requirements of.

[0032] a lower surface of the combination of specific embodiment speaking the invention the ultra material effect of. In one embodiment image picture 4 5 in each * value are respectively: Ohmic electrode line of the strip line h1 = 20 95mm line width w1 of o m = 3 mm to the frame *** 310 the parallel line the line length h2 = 21 than line width w2 = o 25 of connecting wire line w = line width is 2 mm

W2 = 0 to 25 between the distance and tier distance x y = j = a 23 5mm artificial micro structure by wire are both made of copper wire and the thickness is o 018mm two layers of base plate each layer of the thickness is 2mm o as material fr4 dielectric constant *** = 4 3 loss angle tangent value = tan delta o 025.

0033 ] and [ with said * number of the multiple resonance ultrasonic material carry out simulation the s * data simulation if the image picture 6. It is comprised of an 6 can be seen the super material in the i i 20ghz 66ghz 2 7ighz when the resonance of the three resonant frequency in the vicinity of the area i 18 *** 21ghz i i 61 *** i 70ghz 70***2 2 7 ighz in the range of the wave coefficient s21 are less than 20db so on these frequency interval of electromagnetic wave is the base to prevent it passes through the.

[0034] when said multiple resonance ultrasonic material i the base board 2 with multiple layers of adjacent base plate 2 is set between the cloth artificial micro structure 3 when the resonant frequency point position will be formed with a band width of the belt the area corresponding to the wave coefficient s21 20db less than the area will expand it is prevented through the electromagnetic wave of frequency range is enlarged. The performance can be used in the electromagnetic wave of the resistance has special requirement the application occasion.
