Hello Amrita,

I apologize for my delayed response.

I adjusted the mesh density by changing the number of mesh cells per wavelength, using values like 6, 10, 14, and 18, as shown in the image you provided.

Regarding the results, I observed the changes in transmission using the sweep function:

 
1. with mesh value 6
 
2. with mesh value 10
 
3. with mesh value 14
 
4. with mesh value 18
 
 
 

From my observations, the results are quite similar across mesh cell per wavelength values of 6, 10, 14, and 18. The reflectance angle is approximately 39 degrees, which is consistent with my calculations. The number of grating orders, transmission rates, and propagation directions for each order are nearly identical.

I am conducting simulations using a 638 nm wavelength with a top layer of SiO2 and a silicon substrate.

Do these results suggest that the simulation has converged and is sufficient for my needs?

Best regards, Miller.
