摘要
本文设计了一个基于超材料的多频带吸波复合结构,该结构由带有空气槽的金、 FR-4以及金的基板构成。利用仿真软件CST研究了该结构的电磁特性。从结构参数、电磁场分布等对电磁吸波机理进行研究并且对其结构进行详细分析。发现通过改变结构参数使该结构改变,能使得吸波器对于不同频率点进行吸收。电磁超材料在电磁隐身技术,航空技术以及电磁污染的治理等领域都有着非常重要的作用。
In this paper,a multi -band absorbing composite structure based metamaterials is designed. The structure is composed of gold,FR-4 and gold substrates with air grooves.The electromagnetic characteristics of the structure are studied by simulation software CST.The electromagnetic absorbing mechanism is studied from the structure parameters and electromagnetic field distribution,and its structure is analyzed in detail. It is found that absorb different frequencies by changing the structure parameters. Electromagnetic metamaterials play an electromagnetic stealth technology,aviation technology and electromagnetic pollution control.
