Abstract

A type of metamaterial composed of a metal waveguide with discrete rod resonators, is investigated in this work for the first time. The simulation results show that the maximum of FOM =-Re(n)/Im(n) reaches 1.12 at the 543.5 nm. For another set of dimensions of the unit cell, the maximum of FOM reaches 1.41 at the wavelength of 721 nm. Our additional large numbers of simulation results show that different negative-index bands in visible wavelengths can be obtained by tuning the geometric dimensions of the unit cell.
