摘要
针对光子晶体在红外隐身方面的结构设计和需求,本工作通过求解麦克斯韦方程,构建多层薄膜系统的光学传输矩阵,为光子晶体在3~5μm和8~14μm处隐身提供材料选择和结构优化的方案。选择高折射率材料Si与低折射率材料MgF_(2),设计[Si/MgF_(2)]_(N)多层膜结构,推导其红外高反射态。从波动光学理论出发,介绍一维光子晶体红外隐身技术的最新进展与相关原理,计算入射角、周期数、尺寸以及折射率四个因素对光子晶体红外隐身效果的影响。结果表明,要在复杂的工作状况下实现红外隐身,除结构优化外,还需注重材料的选择。
Aiming at the structural design and requirements of photonic crystals in infrared stealth,the optical transmission matrix of multi-layer thin film system is constructed by solving Maxwell equations,which provides a solution of material selection and structure optimization for photonic crystal stealth at 3—5μm and 8—14μm.The infrared high reflection state of[Si/MgF_(2)]_(N)multi-layer was deduced by selecting high refractive index material Si and low refractive index material MgF_(2).Starting from the wave optics theory,the latest progress and related principles of one-dimensional photonic crystal infrared stealth technology are introduced.The effects of incident angle,period number,size and refractive index on the infrared stealth effect of photonic crystal are calculated.The results show that,besides structural optimization,the choice of materials also need paying attention to in order to achieve that the infrared stealth in complex working conditions.
