Let’s walk through a classic benchmark: .
Before clicking buttons, it is essential to understand what the software is doing. The FDTD method solves Maxwell’s equations in time and space. It divides the simulation volume into a rectangular grid (the ). lumerical fdtd tutorial
Before running, check the required resources. Let’s walk through a classic benchmark:
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 It divides the simulation volume into a rectangular
While simple plane waves suffice for basic transmission, the is the powerhouse for scattering problems.
