摘要
设计了一种微波频段多频段超材料吸收器,该吸波器可工作在电磁波平行入射状态,可用于传输电路电磁波的吸收。利用CST软件仿真,模拟了图形层结构单元包含不同数目金属环时该超材料的吸收谱。结果表明,图形层的金属环数目越多,吸收谱上吸收峰数目越多。进一步研究表明每层金属环的引入,都会增加电感和电容,进而增加谐振频率,使谐振峰增加。以上结果表明,该吸波器结构在频谱分析和多谱成像等领域表现出较大潜能。
A multi band metamaterial absorber for microwave band is designed. This absorber can work in the parallel incidence state of electromagnetic wave and can be used to absorb electromagnetic wave in transmission circuit. CST software is used to simulate the absorption spectrum of the metamaterial in the graphic layer structure with different number of metal rings. The results show that the more the number of metal rings in the patterned layer,the more the absorption peaks on the absorption spectrum. Further studies have shown that the introduction of each layer of metal ring will increase inductance and capacitance,and then increase the resonant frequency,so that the resonance peak increases. The above results show that the structure of the absorbe exhibits great potential in spectrum analysis and multi spectral imaging.
