Present Status and Prospect of Rader Absorbing Materials

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.
