平板抗电磁辐射材料反射性能的研究及设计

Research and Design of Reflection Properties on Anti-electromagnetic Radiation in the Plate Absorbing Material

给出了抗电磁辐射平板吸收材料的反射系数公式,并利用MATLAB软件进行了优化设计.设计结果表明,只要选取μ和ε较小值的电磁损耗平板材料就可以使频率在2-18GHz的电磁波的后向反射率达到5dB的工程要求.同时本文的研究和设计方法也为工程上材料的选择与设计具有很好的指导性.

In this paper,the reflection coefficient formula of anti-electromagnetic radiation was given in the flat absorbing material.And the Matlab software was used to optimize the design.The design results showed that if we wanted to get the 5dB of the reflectivity in the engineering requirements we just selected which had the smaller μ and ε value of the electromagnetic losses plate material in the 2-18GHz of frequency.At the same time,this research and design methods could give a good guidance for material choice and design in the engineering.
