i use a plane wave as source i would now like to use the effect of polarisation…which can be done by changing the angle…if i dont want any polarisation how can it be done?
If you want to simulate an unpolarized beam or plane wave you can use two orthogonally polarized beams as explained here.
Hope this helps!
Yes, you can use the two sources in your simulation file, but you need to run two separate simulations activating only one of them at a time. The reason is that we want to add the fields from the two simulation incoherently so we can’t have the two sources acting at the same time. The script file in this example shows how to run the two simulations.
