| 摘 要： | 设计和制作了一种基于超材料的光学透明和双波段吸波体,吸波体基本单元由ITO 十字微结构加补丁结构、玻璃及ITO 膜组成。采用时域有限差分法,研究了十字微结构加补丁结构参数对吸波体电磁性能的影响。仿真结果表明,补丁结构的加入,可以实现双波段高效吸收电磁波,材料在8.5 ~11 GHz 和14.5 ~16.5 GHz 频率范围内反射率小于-10 dB。根据仿真结果,制作了透明吸波体样品,测试了材料反射率和透光率,测试反射率结果与仿真结果吻合得较好,且在可见光区及近红外区透光率达到70%以上。

| Abstract: | A kind of optically transparent and dual band absorber based on metamaterial,which contains ITO cross structure with patches,glsss and ITO backing,is designed. Effect of the parametric of cross-structure with patches on the absorption properties of the absorber are simulated and analyzed by FDTD methed. The simulation results indicate that a bandwidth of reflectivity below -10 dB can be achieved over the frequency range of 8.5 ~11 GHz and 14.5 ~16.5 GHz, it is able to absorb microwave in dual band. In the end, an absorber sample is fabricated based on the design. It is found that the experimental result is well consistent with the design requirements. The transmittance of the sample structure is above 70%. |
