ABSTRACT:
The Terahertz Polarizer structure of the present invention comprises of: A pair of parallel quartz layers for forming a rectangular cube with internal space, then a birefringent liquid crystal is placed in the internal space and sealed, and a pair of permanent magnets with reverse polarities are placed at both sides of the pair of fused silica layers.
