Define your materials, structures, and solver parameters.
The FDTD method is based on the following steps:
to select from pre-defined models like Silicon (Si) or Gold (Au). Ensure the "Mesh Order" is set correctly for overlapping objects. 2. Simulation Region & Meshing FDTD Solver : Add an FDTD simulation region. Set the tab to cover your device. Boundary Conditions : For most photonic chips, use PML (Perfectly Matched Layer) to absorb outgoing waves and prevent reflections. Use Symmetric/Anti-Symmetric boundaries to save memory if your design is periodic. Mesh Settings
However, the software's power is matched by its complexity. This aims to bridge the gap between theory and practice. By the end of this guide, you will understand the core workflow, from geometry setup to data extraction.
