多波段兼容隐身用光子晶体研究进展

Photonic crystal is a kind of functional material composed of various materials with different permittivity. The electromagnetic wave with frequency in the forbidden band of photonic crystal can't propagate in photonic crystal, which shows a high reflection characteristic. The electromagnetic waves in the frequency range of photonic crystal pass through the photonic crystal, which shows a high transmission characteristic, and the propagation of electromagnetic waves can be controlled by artificial construction of defects in the photonic crystal. In order to clarify the problems and opportunities for the further development of multiband compatible stealth photonic crystal materials, the research progresses on photonic crystals in multiband infrared stealth, laser/infrared compatible stealth, radar/infrared compatible stealth, and visible/infrared compatible stealth are reviewed, and the development of a new generation of photonic crystal compatible stealth technology is prospected.
