- You might want to post your .mph file to the forum.
- I'm confused by your 3-component specification of the electric field. Do you have detailed pictures of your geometry, the desired incident wave-vector (k) direction, and your coordinate system?

My .mph file is too big but this is my structure.

- I don't understand why you have a periodic port anywhere in this model.
- Also, I still don't understand your specification of the vector electric field. Among other questions, why would you set Ey = 1 ? I encourage you to re-think your vector analyses here.
- You can reduce the size of your .mph file by selecting "study" from the top toolbar, then "clear all solutions" from the ribbon, then select "mesh" from the toolbar and then "clear all built meshes" from the ribbon. If you then save that file, it will almost certainly be less than 5 MB.

Thank you so much! This is my mph file. The previous formula is for alpha = 0 but in this file I derived E for having both alpha and theta. I hope I didn't make any mistake.

Well, I don't have the wave optics module, but now I can see why you want to use periodic ports (which will model an infinite array -- this may differ somewhat in behavior from the finite array in the earlier picture that you posted). Anyway, it helps the forum that you posted the model. I encourage those who have the wave optics module to take a look at your file and to offer suggestions.
