発明の名称 (英語) WIRE GRID DEVICE
発明の概要(英語) [Problem] To achieve transmitted power characteristics and a power extinction ratio that are not conventionally achievable in the terahertz band. [Solution] A plurality of grid plates 20 having a long and narrow grid section 20a that is formed between one end and the other end of a rectangular thin metal plate are formed by providing a cutout section 20b between the one end and the other end. A stacked grid plate body 2a is configured by stacking the grid plates 20 so that the grid sections 20a of said grid plates 20 face each other with a predetermined gap therebetween. On this occasion, the grid sections 20a are configured as parallel flat plates by inserting spacers 21 between the one ends and between the other ends of grid plates 20 that are adjacent to each other. The stacked grid plate body 2a that comprises parallel flat plates operates as a polarizer in the terahertz wave band.
