摘要
雷达吸波材料是隐身技术的关键材料,雷达吸波材料的研究越来越受到世界各国的高度重视。本文介绍了雷达吸波材料的定义、工作原理与实际要求。对超微磁性金属粉、磁性纤维、六方铁氧体、导电聚合物、手性材料、智能材料等主要的雷达吸波材料体系的研究现状进行了评述。
Radar Absorbing Materials (RAM) is the key materials for stealth technique, and more and more attentions have been paid to RAM since 1990's in world. The definition, working principle and requirements of RAM have been introduced. Present research status of some important material systems, including magnetic metal microparticles, magnetic fibers, hexagonal ferrites, conducting organic materials, chiral materials, smart materials and so on, are reviewed. Finally, the prospect of RAM is discussed in the paper.
