Abstract
We propose a broadband reflective metamaterial polarization converter which is composed of arrays of split-ring resonators (SRRs), a dielectric layer and a continuous metallic layer. For the case of a loss-free dielectric layer, the average transformation rate is around 90% at frequencies from 6.68 to 10.91 GHz, and the bandwidth is 56.66% of the central wavelength. The increased loss tangent of the dielectric layer is shown to induce a reduced transformation rate due to enhanced absorption.
