Abstract
A wire grid device having transmission power characteristics and a power extinction ratio in a terahertz wave band that cannot be achieved conventionally. A cutout is formed between one end and an opposite end of a rectangular metal thin plate to form a plurality of grid plates each having an elongated grid part between the one end and the opposite end. The grid plates are stacked in such a manner that the grid parts of the grid plates are spaced at a given interval and face each other, thereby forming a grid plate stack. In this case, spacers are inserted between one ends and between opposite ends of adjacent ones of the grid plates to form parallel flat plates configured by the grid parts. The grid plate stack forming the parallel flat plates operates as a polarizer for a terahertz wave band.
