六角结构磁铅石铁氧体吸波机制的设计与研究

STUDY AND DESIGN OF ABSORPTION MECHANISM ON HEXAGONAL STRUCTURE WITH MAGNETO PLUMBITE TYPE FERRITE MATERIAL BY ELECTRON-WAVE ABSORBING

利用离子复合取代和控制物相平衡转化的方法，制成六角结构磁铅石多元铁氧体吸波材料，用于航空、航天隐身技术与抗电磁辐射技术中.文中探讨了吸波机理以及测定了吸收体晶体结构，并说明吸收频率与厚度等诸参数关系.文中采用宏观与微观相结合的分析方法，其结果与设计相符.

By means of ion ally substitution and crystal phase equilibrium transformation we have prepared the hexagonal polycrystalline ferrite which can be used in the aircraft industry,spacetechnology,the concealment and anti-electromagnetic radiation technology. This paper also studies the mechanism of absorbing the electromagnetowave,the crystal structure of the absorbents,and the relation between the absorptive frequency and the thickness of the film. By combining the macro-observation with micro-analysis,the test results are in agreement with the design.
