| description | The present invention provides a polarization-independent terahertz wave control element, and provides a method for manufacturing a polarization-independent terahertz wave control element. The present invention provides a terahertz wave control element comprising: (A) a first flat plate having (A1) a first substrate, (A2) a first electrode formed on the first substrate, and (A3) a first liquid crystal alignment film formed on the first electrode; (B) a second flat plate having (B1) a second substrate, (B2) a second electrode formed on the second substrate, and (B3) a second liquid crystal alignment film formed on the second electrode; and (C) a liquid crystal present in a space formed by disposing (A) the first flat plate and (B) the second flat plate parallel to each other with a predetermined distance therebetween so that the first and second liquid crystal alignment films face each other, wherein (D1) the terahertz wave control element has a first portion in which the liquid crystal is aligned in a first direction parallel to (A) the first flat plate and (B) the second flat plate, and a second portion in which the liquid crystal is aligned in a second direction orthogonal to the first direction and parallel to (A) the first flat plate and (B) the second flat plate when no voltage is applied, (D2) the first portion has a first width, the second portion has a second width, the first and second portions are disposed adjacent to each other and alternately disposed in a predetermined cycle, (D3) when voltage is applied, the liquid crystal in each of the first portion and the second portion is aligned in a direction orthogonal to (A) the first substrate and (B) the second substrate, and (E) a phase change in which a terahertz wave transmitted through the terahertz wave control element is independent of the state of polarization. |
