In this paper microwave experiments are performed to verify the circular polarization dependent electromagnetically induced transparency (EIT) phenomenon in chiral plasmonic metamaterials. Both numerical simulation and microwave experiment demonstrate that, the EIT spectrum only emerges for only one of the circularly polarized lights, either the left-circularly-polarized or the right-circularly-polarized ones. Consequently, the obvious difference of transmission spectra for these two circularly-polarized waves leads to large circular dichroism in our very thin structures. Therefore, the chiral EIT medium may be promising for the slowing down or capturing of certain circularly polarized light.
