Abstract:

The photonic band gap and photon localization characteristics of photonic crystal structures prevent electromagnetic waves within the band gap from propagation. According to the excellent performance, the photonic crystal provides an important means for achieving infrared stealth of targets. Based on the structure and process characteristics of photonic crystal, this paper summarized the existing mechanisms, and design methods, for regulating the infrared spectral characteristics of photonic crystal. Meanwhile, the types of material, including periodic structure optimization, introduction of metal materials, compound materials, plasma, and superconducting materials were reviewed. Furthermore, the applications in regulating the infrared band gap of photonic crystal were also introduced.At last, the development of photonic crystal was expected to provide reference for the needs of photonic crystal in band gap regulation and target stealth.
