FDTD Note
1. Open FDTD
- Initial project is 3D project
2. Add Simulation Region
- Background index
- Geometry
- Mesh settings
- Boundary conditions
- z direction use PML
- x, y direction use Periodic
if want to simulate tilt angle light sourse (like SA)
** we must use Bloch **
3. Add Structure
- Geometry
- Material index
- Rotations
4. Add Source
- General
- Plane wave
- angle, direction
- Geometry
- Wavelength
5. Add Monitor
- Refractive index
- Movie
- Refractive index
6. loop
- sweep
