中文摘要：

利用电化学沉积自组装法制备了具有纳米银树枝结构单元的超材料吸收器。该吸收器采用＂金属谐振结构单元层-绝缘层-金属层＂复合结构,由直径70～140nm、非周期排列的银树枝结构单元,与聚乙烯醇绝缘层和纳米银金属层组合而成。通过改变电化学沉积过程中的条件,如沉积电压和聚乙二醇-20000浓度,可以实现对超材料吸收器吸收频率点数量和吸收强度的可控调节。实验表明这种吸收器可在538和656nm实现强度为21.1%和24.8%的多频吸收。这种超材料吸收器具有制备工艺简单,制备成本低廉,样品工作面积大等特点。

英文摘要：

Electrochemical deposition self-assembly method was used to fabricate a metamaterial absorber with nanoscale silver dendritic pattern unit.The metamaterial absorber is consisted of ＂unit-dielectric-metal＂ structure,which contains randomly distributed silver dendritic pattern units with diameters of 70-140nm,PVA dielectric interlayer and nanoscale silver metal plane.By means of changing the deposition conditions,such as deposition voltage and concentration of PEG,the absorption peak quantity and absorption magnitude of the metamaterial absorber can be modulated.The experiment result shows that the absorber can realize multi-frequency absorption at 538 and 656nm with the magnitude of 21.1% and 24.8%.The fabrication of this large structure area metamaterial absorber has the advantages of easy processing and low cost.
