Abstract

We reply to the comment written by Aslam and Güney on our previous paper, Zhao et al. [Opt. Express 19(12), 11605-11614 (2011)]. We maintain that the proposed implementation of the DE algorithm for NIMs optimization in our work is correct, and the mentioned ambiguities in the comment due to the existence of multiple branches for n' in the retrieval procedure have been considered and eliminated by using the proposed robust retrieval method. Furthermore, the FOM of 15.2 for the DE-designed optimal fishnet structure reported in our work is reasonable for ideal fabrication conditions.
