Lumerical Fdtd Tutorial -

Ansys Lumerical FDTD

This draft post provides a comprehensive overview of the workflow, designed for researchers and engineers transitioning from theoretical Maxwell's equations to practical optical device simulation.

1. Launch Lumerical FDTD and create a new project.
2. Choose the "2D" simulation type and set the units to "um" (micrometers).
3. Set the simulation domain size to 10 um x 10 um.
4. Set the grid size to 20 nm x 20 nm.
5. Choose the "TM" polarization (electric field in the z-direction).
