In this tutorial, the focus shifts to a comparative analysis between the results derived from FDTD and Rigorous Coupled-Wave Analysis (RCWA). Beginning with a brief overview of the periodic waveguide structure under study, the video demonstrates how to set up simulations for both methods. Emphasis is placed on aligning the settings and parameters to ensure comparability. By the end of the session, viewers will appreciate the similarity in results from both methods, underscoring the reliability and robustness of optical simulations.
