中文摘要：
为了在同一结构中同时实现负介电常数和负磁导率（双负）,采用一种“巨”字形结构,利用丝网印刷技术在氧化铝基板上进行加工制作,并通过仿真和实验测试证实了这种结构的“双负”特性.与利用磁谐振器和电谐振器组阵实现左手材料的方法相比,这种单一结构可以同时实现负介电常数和负磁导率,制作方便,等效电路简单,双负频段较宽.利用丝网印刷技术进行样品的制作,工艺简单,成本低廉.
英文摘要：
To realise simultaneously negative permittivity and negative permeability in one structure,there must exist both electric resonance and magnetic resonance in the same band for the structure. Based on this principle, we fabricated a structure and investigated its !double-negative characteristics by means of numerical simulation and experimental test. Compared with other left-handed metamaterials, this structure exhibits simultaneously negative permittivity and negative permeability and its equivalent circuit is much simpler. Moreover, it has much broader left-handed pass-band in which both the permittivity and the permeability are negative. The structures were fabricated by using screen-printing technology, which is much easier and economical.
