PROBLEM TO BE SOLVED: To provide a laminated wire grid capable of improving the extinction ratio and increasing the bandwidth.SOLUTION: A laminated wire grid 1 separates polarization components in a terahertz wave region, and includes a first wire grid 2A and a second wire grid 2B stacked on the first wire grid. The first wire grid has a plurality of first wires 4A arranged along one direction at an interval d shorter than an adaptive wavelength. The second wire grid has a plurality of second wires 4B arranged along one direction at the interval d. The distance L between the plurality of first wires and the plurality of second wires is the interval d or shorter. |
