摘要： This invention is intended to provide a sheet-type metamaterial of a film configuration to exhibit a figure of merit (FOM) exceeding 300 in a terahertz wave band. A film-shaped dielectric substrate 12 has a front surface on which a first wire array 10 is formed, and a back surface on which a second wire array 11 is formed. The first wire array 10 includes elongated metallic first cut wires 10a of a predetermined length l aligned in a y-axis direction with a gap g therebetween and in an x-axis direction with space s therebetween. The second wire array 11 includes second metallic cut wires 11a having the same shape as the first cut wires 10a and aligned so as to overlap the first cut wires 10a. With a thickness d of the dielectric substrate 12 set at about 50 µm, the length l of the first cut wire and the second cut wire is a length approximate to a value to generate resonance at a design frequency.

摘要： [Problem] To achieve transmission power characteristics and a power extinction ratio in a terahertz wave band that cannot be achieved conventionally.
[Solution to problem] A cutout 20b is formed between one end and an opposite end of a rectangular metal thin plate to form a plurality of grid plates 20 each having an elongated grid part 20a between the one end and the opposite end. The grid plates 20 are stacked in such a manner that the grid parts 20a of the grid plates 20 are spaced at a given interval and face each other, thereby forming a grid plate stack 2a In this case, spacers 21 are inserted between one ends and between opposite ends of adjacent ones of the grid plates 20 to form parallel flat plates configured by the grid parts 20a. The grid plate stack 2a forming the parallel flat plates operates as a polarizer for a terahertz wave band.
