Abstract :
A periodic structure of nanoholes in a continuous sheet of graphene over a silicon substrate is analyzed and its application as a terahertz (THZ) polarizer is demonstrated. The effect of the hole geometry on the extinction ratio and the working frequency of the polarizer is investigated. This periodic structure is then used in a double layer structure to realize a substrate-based polarizer with a higher extinction ratio and bandwidth as compared to the single layer configuration. The small thickness of substrate-based structures (2μm) ensures that the Fabry-Perot multi-reflections will not happen in the proposed polarizer.
