摘要
A method to fabricate multilayer terahertz polarizer was proposed. The polarizer was composed of subwavelength metal gratings on polyethylene terephthalate (PET) film by layer-by-layer-sticking. The terahertz time domain spectroscopy (THz-TDS) measurement reveals that the triple-layer polarizer have an average extinction ratio of 75 dB and an average transmittance of 75% in 0.1-2 THz. Comparing with the single layered device, the extinction ratio of the multilayer THz polarizer is remarkably increased while the transmission is little changed.
