摘要
光子晶体是一种新型的人工结构功能材料,其光子禁带对入射电磁波具有高反射率,能够有效改变目标的辐射特性,降低目标在红外波段的可探测性,是未来红外隐身技术的重点发展方向。为理清光子晶体红外隐身材料进一步发展所面临的问题和机遇,对光子晶体在红外辐射特性调控、光子禁带的展宽、多波段兼容技术、变发射率自适应隐身技术等方面的应用进展进行梳理和总结,并对新一代光子晶体红外隐身材料技术发展进行了展望,以期为光子晶体红外隐身材料对宽频隐身、多波段兼容、可逆的动态调整等的需求提供一定的解决思路。
Photonic crystals are a kind of artificial functional materials with potential and promising application in the infrared stealth technology,of which photonic band gap has high reflectivity to electromagnetic waves. The photonic crystals can alter the radiation characteristics of targets and protect the targets from being detected in infrared region. In order to clarify the problems and opportunities in the further development of photonic crystal and provide some proposals for the requirements of infrared stealth materials for wide band,multi band compatibility and reversible dynamic adjustment. The applications of photonic crystal in the regulation of infrared radiation characteristics,the broadening of photonic band gap,the multi band compatible technology and the adaptive stealth technology with variable emissivity are reviewed and summarized. Finally,the new generation of photonic crystal infrared stealth materials is prospected.
