卡耐基—麦伦大学的研究者们发现了一组以非铁氧体为基底的材料,该材料能吸收雷达辐射,并能减少飞机雷达反射80％。该材料,视黄基席夫碱(retinyl schiif base)盐,是一些含有双键碳-氮结构的聚合物,碳氮结构联结分子聚烯链的线性主链中的二价基团。据该大学的分子电子学中心主任,该盐的射频吸波特性的发现者,罗伯特·R. 伯奇教授讲,该盐是一种高极性、黑色并且类似石墨的物质。“这些盐的重要性在于,其射频能量吸收能力与铁氧基、低观测性材料的相当,甚至更
Researchers at Carnegie-Mellon University discovered a group of non-ferrite-based materials that absorb radar radiation and reduce aircraft radar reflections by 80%. This material, the retinyl schiif base salt, is a group of divalent groups in the linear backbone of some carbon-nitrogen-containing structurally bonded molecular polyolefin chains that contain double bond carbon-nitrogen structures. According to Prof. Robert R. Burge, director of the University’s Center for Molecular Electronics, the inventor of the radio-frequency absorption properties of the salt, the salt is a highly polar, black and graphite-like substance. "The importance of these salts is that their radio frequency energy absorption is comparable to that of ferroxy, low-observability materials, and more
