An ultrathin terahertz quarter wave plate with high transmittance by flexible metamaterial

摘要

An ultrathin Terahertz (THz) quarter wave plate with high transmittance by flexible metamaterial is proposed in this paper. The device employs double layers of split ring resonator (SRR) with a polymer as the substrate. Due to the anisotropy of the SRR, it obtains a quarter wave plate with the transmittance of 0.72 and the ellipticity of 0.9994 at 0.854 THz from simulation. The device has a thickness in sub-wavelength of 50 μm.
