摘要
应用数值方法对特殊光子晶体-蓝蝴蝶翅膀微结构的光学散射角偏特性进行了深入研究。根据蓝蝴蝶翅膀的表皮微结构简化模型,应用时域有限差分(FDTD)方法对其在自然光照射下的散射角偏特性进行了分析,深入研究了此光子晶体中各结构参数对光散射角偏特性的影响,详细探讨了该光子晶体的角偏特性散射机理及其在军用目标隐身设计中的应用。
The angle-dependent characteristic of electromagnetic (EM) scattering from photonic crystal with the microstructure of morpho butterfly's wing is investigated. The optical scattering properties are analyzed with the simplified model for surface microstructure of morpho butterfly's wing and finite difference time domain (FDTD) method. Furthermore, the influence of structural parameters on angle-dependent characteristic is studied. The reasonable explanation is presented for the angle-dependent electromagnetic scattering mechanism and its application in the stealth design of military targets are also discussed.
