A kind of photonic crystal (PC) film, which is compatible stealth in middle and far infrared bands, is designed and prepared based on the transfer matrix method and the evaporation film technology. The practical thicknesses and the middle and far infrared spectral characteristics of this kind of PC thin film are measured, which are in a good agreement with the theoretical design values. The results show that, compared with two kinds of conventional infrared stealthy material as the infrared stealth coatings and the conventional camouflage fabrics, the PC film has the strongest ability to suppress infrared radiation at both middle and far infrared bands. The influences of outdoor environment irradiation on the stealth effects of PC film at the bands of 8-14 μm and 3-5 μm are relatively weak.
