摘要/Abstract

摘要： 通过辊压成型工艺制备了以MZ、炭黑为吸波剂的聚氨酯基吸波贴片,研究了吸波剂配比对吸波贴片电磁、吸收特性的影响,进一步探讨了吸波贴片衰减入射电磁波的机理。结果表明:随吸波剂填充量的增加,ε′等电磁参数明显增大,一方面增强了吸波贴片的衰减特性,另一方面削弱了其与自由空间的阻抗匹配程度;吸波贴片对入射电磁波的干涉作用导致其吸收峰位置随吸波剂含量、贴片厚度增加而趋向低频;1.5 mm厚、填充80wt%MZ的吸波贴片具有良好的吸波性能,其反射率在9.18 GHz～17.37 GHz频段低于-10 dB,基本满足水面舰艇在X、Ku波段的雷达隐身需求。

Abstract: In this work, an PU absorbing patch, filled with MZ and carbon black as the absorbent, was prepared by rotational moulding process. The influence of absorbing agent on the electromagnetic and absorbing property of the absorbing patch was analyzed. Furthermore, the microwave absorbing mechanism of the absorbing patch was discussed. Finally, the results show that the increase of absorbing agent content will cause the improvement of attenuation characteristic, and simultaneously, will cut down the impedance matching between absorbing patch and free space. The destructive interference result in the position of absorption peak tends to low frequency direction, with the increase of the absorbing agent content or thickness of the absorbing patch. An PU absorbing patch, with 1.5 mm thickness and filled with 80wt% MZ as the absorbent, has the best absorbing property, whose reflectivity is less than -10 dB between 9.18 GHz and 17.37 GHz, and could basically meet the requirement of warship keeping radar stealth in the X and Ku band.

Key words: absorbing patch, attenuation characteristic, impedance matching, interference, radar stealth
