铁氧体/石墨复合吸波涂层的微波吸收性能
Microwave Absorbing Properties of Ferrite/Graphite Composite Coatings
摘要
Abstract
Magnetic loss-type Ba0.9Sm0.1Co2Fe16O27 ferrite prepared by the solid state method and electric loss-type graphite were combined,and the electromagnetic parameters were tested.In addition,the reflectivity of the double layer composite coating was successfully simulated by YRcomputor software.It is shown that the ferrite/graphite composite coating exhibited excellent microwave absorbing properties in 2 ~ 8 GHz band.When the lower layer was 80 wt% Ba0.9Sm0.1Fe12O19 with a thickness of 1.5 mm and the upper layer was 10 wt% graphite with a thickness of 1.5 mm,the composite coating showed great microwave absorbing properties.The maximum value of reflection loss（RL） was-27 dB,and the frequency width reached to 3 GHz（3.5 ~ 6.5 GHz） when RL was below-10 dB.关键词
