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
