TLDR
In this article, a single/dual/triple band absorber based on wire structure is presented, which is polarization insensitive due to four fold rotational symmetry in the design.Abstract:
In this paper, design, fabrication and measurement of single/dual/triple band absorber based on wire structure is presented. The absorber consists of one/two/three metallic wires for single/dual/triple band absorption. These metallic wires are printed on lossy FR4 sheet backed with metallic plate. The resonant frequency is tuned by changing metallic wire length. The proposed absorbers are polarization insensitive due to four fold rotational symmetry in the design.read more

Unifying approach to left-handed material design.
TL;DR: In this paper, the authors show that equivalent circuits offer a qualitative and even quantitative simple explanation for the behavior of various types of left-handed (or negative-index) metamaterials and apply this unifying circuit approach in accounting for the features and in optimizing the structure employing parallel metallic bars on the two sides of a dielectric film.
