Polarization-independent electromagnetically induced transparency-like effects in stacked metamaterials based on Fabry-Perot resonance

Abstract

We propose a scheme for realizing plasmonic electromagnetically induced transparency (EIT)-like effects at optical frequencies in a stacked metamaterial that consists of two silver rings. The two silver rings are excited strongly by an incident wave. Based on Fabry-Perot (FP) resonance coupling between the two resonators, polarization-independent EIT-like effects appear at optical frequencies.
