在共面波导上加载集总电容电感制备单负材料

为了探索实现单负材料的方法,研究了在共面波导上加载集总电容和电感元件制备单负材料。首先通过理论分析和微波实验,证实了在共面波导上周期性地加载集总电容和电感元件能够实现两种单负材料(电单负材料和磁单负材料)。然后,针对该制备方法,进一步研究了加载电容电感周期性的破坏及加载电感对称性的破坏对单负带隙的影响。结果表明:周期性的破坏对单负带隙基本没有影响;对称性被破坏后,如果电感分布在共面波导中心导带的两侧,仍然能够获得单负材料。

Fabricating single-negative materials by loading lumped-elements of capacitors and inductors on coplanar waveguide

In order to explore the methods of realizing single-negative(SNG) materials,the fabrication of the SNG materials using coplanar waveguide(CPW) with loading lumped-elements of capacitors and inductors was studied.First,it was illustrated through theoretical analysis and microwave experiment that the SNG materials,including epsilon-negative materials and mu-negative materials,can be realized by loading lumped-elements of capacitors and inductors on CPW periodically.Then,it was also investigated that whether t...
