Abstract

The invention provides a wave-transparent structure with controllable electromagnetic performance, the wave-transparent structure comprises a first compact layer, a three-dimensional lattice interlayer and a second compact layer which are sequentially arranged from top to bottom, and the density of the first compact layer and the density of the second compact layer are both higher than the densityof the three-dimensional lattice interlayer. According to the technical scheme, the middle interlayer of the wave-transparent structure is the three-dimensional dot matrix interlayer, the dielectricconstant of the wave-transparent structure can be reduced, the electromagnetic performance of the wave-transparent structure is improved, the wave-transparent performance of the wave-transparent structure is improved, and the electromagnetic performance of the wave-transparent structure is controllable based on the internal structure of the three-dimensional dot matrix interlayer; and meanwhile, the light weight of the wave-transparent structure is realized on the basis of meeting the bearing requirement.

Description

technical field [0001] The invention relates to the technical field of wave-transmitting materials and structures, in particular to a wave-transmitting structure with controllable electromagnetic properties. Background technique [0002] Existing wave-transparent structures are usually dense hierarchical structures. According to established methods such as hand-weaving of wave-transparent materials, the interlayer combination structure is obtained. Through ablation or hot pressing, the dielectric properties of the materials often determine the wave-transmission performance of the structure. It is difficult to further improve the wave transmission characteristics. [0003] At present, in order to improve the wave-transmitting characteristics of the wave-transparent structure, a pore-forming agent is added to the dense wave-transmitting structure, and the pore-forming agent is volatilized and escaped during the reaction sintering process to form pores to reduce the dielectric ...
