▎ 摘　　要

NOVELTY - The converter has a substrate provided with a silicon dioxide isolation layer. The silicon dioxide isolation layer is fixed with a top surface of a single graphene layer. The single graphene layer is formed in a rectangular hole. Length and width of the rectangular hole is 100-140nm and 80-120nm. Angle is formed between an edge of the substrate and the rectangular hole. Included angle is formed between the silicon dioxide isolation layer and the single graphene layer. USE - Bandwidth tuning infrared polarization converter. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a bandwidth tuning infrared polarization converter.
