主　　题：microwave absorption infrared stealth photonic crystal compatible stealth 

摘      要：Traditional stealth materials do not fulfill the requirements of high absorption for radar waves and low emissivity for infrared ***,they can be detected by various technologies,considerably threatening weapon ***,a stealth material compatible with radar and infrared was designed based on the photonic bandgap characteristics of photonic *** radar stealth lay-er(bottom layer)is a composite of carbonyl iron/silicon dioxide/epoxy resin,and the infrared stealth layer(top layer)is a 1D photonic crystal with alternately and periodically stacked germanium and silicon *** composition optimization and structural adjust-ment,the effective absorption bandwidth of the compatible stealth material with a reflection loss of less than-10 dB has reached 4.95 *** average infrared emissivity of the proposed design is 0.1063,indicating good stealth *** theoretical analysis proves that photonic crystals with this structural design can produce infrared waves within the photonic bandgap,achieving high radar wave transmittance and low infrared *** stealth is achieved without affecting the absorption performance of the radar stealth layer,and the conflict between radar and infrared stealth performance is *** work aims to promote the application of photonic crystals in compatible stealth materials and the development of stealth technology and to provide a design and theoretical found-ation for related experiments and research.
