Abstract
We engineered numerically a dualband negative index metamaterial exhibiting polarization independence based on a double square ring pairs array and thin wire net pairs. The mechanism accomplishing the negative refractive index was interpreted using retrieved optical constants together with monitored field distribution. The influence of the substrate on the effective material parameters has also been analyzed qualitatively at the end of this work.
