摘要: 控制优化电磁参数是实现高性能单层电磁波吸收体的关键。本文通过电磁波吸收理论对S带介电型电磁波吸收体的电磁参数与吸收的相关性进行了探索。研究表明:在预设吸波材料高反射率的条件下,可以对材料参数进行优化设计,反推得到预期频带下达到预定反射率所需的理想电磁参数区域,进而可以选择材料进行高性能吸收材料的制备。本研究对于吸波材料的设计与制备具有重要的指导意义。Abstract: In this paper the correlation between electromagnetic parameters and absorption about dielectric-type electromagnetic wave absorber in S band are researched on the basis of electromagnetic wave absorption theory.Under the conditions of intended high-reflectivity,the electromagnetic parameters are optimized,and the ideal complex permittivity region is determined is determined to achieve the intended reflectivity under a certain frequency bands,and then proper materials for preparation of high-performance absorber are introduced.The research may have on important guiding significance for absorbers design and preparation.
