Abstract

Rigorous coupled-wave analysis (RCWA) was utilized to analyze the effect of pieced-up wire-grid polarizer (WGP). By using the strategies developed in this study, RCWA can model the WGP patches with the diffraction efficiencies satisfying the energy conservation rule and the accuracy requirement. An example of a 100-nm-period WGP demonstrated an extinction ratio of 1000 numerically, whereas the approach of RCWA integrated with the proposed strategies was proven to be superiorin simulation speed and presented benefits for designing WGP patches.
