Description

The frequency selection textile of X-band communication, the preparation method and application of textile
Technical field
The present invention is led on the X-band of selectively permeable X-band signal of communication, the other frequency electromagnetics of cut-off a kind of Application of frequency the selection textile, the preparation method and the textile of textile of letter on traffic guidance's tent etc., is related to spinning Fabric technical field.
Background technology
The frequency-selective surfaces (FSS) for typically forming the conductive unit of given shape or non-conducting unit periodic arrangement, Can selectively by some frequency electromagnetics, end the structure of other frequency electromagnetics, in communication window, antenna, radar The numerous areas such as reflecting surface, wave filter obtain important application, are the study hotspots of electromagnetism specialty.At present, frequency-selective surfaces Research and prepare be limited to rigid material, for example open on a metal plate in the enterprising row metal paster of rigid media or periodically Hole, formation have the shortcomings that hard matter, processing difficulties, are not easy MULTILAYER COMPOSITE.It is generally false in order to obtain good frequency selective characteristic Array periodic structure on infinity plane is set to, i.e. the periodicity of periodic structure is enough, can avoid the unfavorable of edge Influence.In addition, the frequency selective characteristic of curved surface periodic structure is increasingly complex, it is more prone to prepare on planar materials and realizes.
For the textile material with function solenoid, existing research is more to concentrate on conduction, dielectric, antistatic, electromagnetic screen Cover etc., more by integrally carrying out top finish, chemical plating, magnetron sputtering or with electro-magnetic screen function to fabric Fiber process reaches the purpose of bulk shielding electromagnetic wave into fabric.Apply lintel Chinese parasol tree et al. and propose textile electromagnetism and electromagnetism weaving The Research Thinking of product exploitation, by metallized fabrics technology, use for reference the periodic structure of frequency-selective surfaces, will such as square, The metallic conduction or non-conductive medium part, cyclic array of the shape such as circle, Jerusalem, dipole are distributed in medium and knitted Thing or conductive fabric surface etc., electromagnetic wave can be achieved the frequency selectivity of textile material is led to thoroughly, and propose basic feasible solution Preparation for processing, this method propose preparation method substantially and feasible general principle, but the tool of frequency-selective surfaces Body design, selection, application requirement etc. are all extremely complex problem in science.
For specific frequency and demand, lead to textile material thoroughly to successfully develop the frequency selection for meeting to require, also need Carefully study the following aspects：1) design cycle planform is needed：Conventional periodic structure has four major classes, including ring Shape, center connection shape, solid type, combined etc., different structure shape needs to be prepared using different methods, and is adapted to spy Fixed purposes, such as, annular periodic structure is not suitable for carrying out direct etching on conductive base, and solid shape periodic structure is uncomfortable Close low-frequency resonant point etc..2) calculating cycle physical dimension is needed：On the one hand, it is right for some specific frequency, different shape institute There is significant difference in the size answered, so as to influence practical performance；On the other hand, each physical dimension of periodic structure corresponds to different Implication, it is impossible to arbitrarily choose, portion size, which crosses conference, causes graing lobe, or easily deforms upon, produces curved surface influence, too small to lead Cause processing difficulties etc..3) need to consider conductive base and non-conductive substrate：Difference, the difference of current-carrying part electrical conductivity of base material are equal The difference of resonant frequency can be caused.4) necessary simulation theory calculates the combination with practical experience：Due to structure and size and base material Combination it is ever-changing, in order to develop material suitable, that there is particular resonance frequency, on known experiential basis, combine Necessary theoretical calculation is essential.
Military field X-band is that radar communication often uses wave band, in 8~12GHz scopes.Generally, in order to prevent electromagnetic interference, Existing tent uses loomage more, and by the reflection to electromagnetic wave, all frequency electromagnetics in shielding wave band are all carried out Stop, not only filtered unwanted signals, also blocking receiving needs signal.Therefore, it is necessary to develop electromagnetic wave selectivity logical account thoroughly Paulin ends the interference signal for filtering other frequency ranges or harm to realize that X-band communicates.Clearly for the selection of specific frequency Property it is thoroughly logical, it is necessary to based on strict theoretical calculation and experimental verification, and select suitable periodic structure, there is more accurate week Phase physical dimension and distribution, supporting suitable specific preparation method etc.；And in application aspect, in order to ensure the periodicity of structure and Flatness, some particular/special requirements.
