Studies On the StealthyFunction of the Carbon Cluster-like Mater ial

摘要: 平面环状碳团簇是一种特殊的大分子 ,计算表明其转动能级变化的谱线富集于 1—2 0GHz的微波区 .利用该特性制得了碳团簇型微波隐身材料 .测试结果表明 ,对于双层材料 ,最小反射率达 -3 1dB ,有效频带宽度为 2 .3GHz,同时 ,将该材料长时间处于自然条件下,其吸波性能稳定. Plane ringed carbon cluster is a special macromolecule. Cal cu lations show that the frequencies of rotational transition of carbon cluster are bound in the area of 1-20 GHz. According to this traits , we made carbon clust er-like microwave stealth material . The testing results indicate that the dou ble layer materials have the least reflectivity value of -31 dB and a wide frequ ency band width of about 2.3 GHz for reducing about -10 dB. Although the carbon cluster material is deposited...
