AbstractA chiral metamaterial based on a double-layer twisted Y shape structure is presented that achieves obvious circular dichroism and giant optical rotation at different frequencies. When a y-polarized wave is incident to this chiral metamaterial, circular dichroism with a great difference between the transmission coefficients for the circularly polarized waves is obtained at 12.28 GHz. Meanwhile, 90° optical rotation is observed at 12.70 GHz, where the incident y-polarized wave is transformed into its cross-polarization with a transmission coefficient of -1.15 dB. Surface current distributions are calculated to demonstrate the coupling between the electric and magnetic fields.
