摘要
Using the finite element approximation of electromagnetic wave propagation problem in frequency domain analysis, we have developed and implemented a finite element model of a terahertz substrate-based wire grid polarizer in a form of unit cell. The proposed polarization unit cell is considered as a waveguide with a specific boundary condition. The model is implemented by the COMSOL software system as a ready to use tool for terahertz polarizers design or refinement. Simulation results show an excellent agreement with known experimental and simulation data. (C) 2021 International Association for Mathematics and Computers in Simulation (IMACS).
