Now I would like to solve the mode on my dielectric grating under single wavelength illumination. The information I would like to get from my simulation is
- The effective refractive index of the grating
- The mode on the gratings
I have several questions about using the mode source.
- What are the setting rules of the mode source?
(the mode source dimension, the boundary condition of every direction and the distance between the source and FDTD box)
- How to make sure the simulation result is correct?
Please see attached file of my settings.
(The mode source is launched from the left side of the gratings and the surface plasmon mode will propagate along the +x direction.)
