Research Progress on Photonic Crystal Infrared Stealth Materials Technology

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.
