摘要:
该文对蓝蝴蝶翅膀在可见光照射下的电磁散射特性进行研究,应用时域有限差分(FDTD)方法结合外延表面技术分别对TE波和TM照射下的翅膀简化模型的电磁散射特性进行分析,验证了这种结构的散射特性。由于其散射特性具备了隐身技术中结构隐身和材料隐身两大特点,所以,对这种蝴蝶结构进行深入研究,充分利用如上特点,有望对新型的高性能隐身材料的研制提供借鉴。
Abstract:
The electrom agnetic ( EM ) scattering of MorPho Rhetenor butterfly is investigated. A simplifiedmodel is obtained and the associated electromagnetic scattering incident by TE mode or TM mode is analyzed w ith finite difference time domain ( FDTD) method combined w ith extensive surface technique. Prospective scattering characteristics are verified. The scattering perform ance of the structure possesses not only the structural stealth but also the material stealth strongpoin.t The result shows that the research on the scattering of butterfly w ing benefits to the development of the stealth technique in China.
