Abstract

Fishnet structure metamaterials are modified by introducing some curvature at the corners of the slabs and the neck lines in order to tailor a uniform current distribution as well as field concentration in the microwave regime. The results obtained show that these modified fishnet structures can generate 20% broader low loss near-zero index bandwidth as compared to that of the original fishnet structures. The majority of the near-zero bands of the modified fishnet structures produce lower loss than those of the original fishnet structures at the same frequency.
