摘要：
We demonstrate a method for manufacturing wire-grid-type polarizers using a general-purpose printer and a general-purpose printing spot-color ink. The transmission characteristics are examined by terahertz (THz) time-domain spectroscopy. The wire grid sheet prepared in this study has a polarization factor larger than 0.90, which is comparable to that of commercial metal wire grids in the sub-THz range. This simple manufacturing method could be applied to one- or two-dimensional metallic photonic crystals.
