摘要：

In this paper, a new type of 3D metamaterial composed of double periodic array of metallic cross-pairs printed on the six sides of a cubic dielectric substrate was proposed to obtain the characteristics of broadband NRI and isotropy for the applications of super lenses. The behaviors of NRI, isotropy and polarization were analyzed using the CST Microwave Studio. The results show that the proposed metamaterial exhibits not only a broadband NRI whose relative bandwidth can be up to 56.7%, but also polarization-independence and isotropy. Thus, the proposed metamaterial is a good candidate material for 3D broadband isotropic NRI metamaterial. (C) 2011 Elsevier BY. All rights reserved.
