摘要
实现宽带吸收是超材料吸波体研究面临的主要问题之一.基于此设计了鱼刺状宽带超材料吸波体,采用商业电磁仿真软件Microwave studio CST对超材料吸波体的吸收性能进行了计算和分析,结果表明设计的鱼刺状超材料吸波体可以在较宽的频率范围内实现电磁波的高吸收,在89.68~94.36 GHz之间吸收率保持在90%以上.结构单元具有简单、较容易制备等优点.
The realization of broadband absorption has been one of the major research problems on metamaterials absorber.The fishbone-shaped broadband metamaterials absorber has been designed in this paper.Using commercial electromagnetic simulation software Microwave Studio CST, the absorption property has been calculated and analyzed.The results show that the fishbone-shaped metamaterials absorber can bring about high absorption over a wide frequency range and the absorption rate can remain at 90% between 89.68-94.36 GHz.It has the advantages of simplicity, being easy to prepare and so on.
