Ansys Insight: Calculating the response to an unpolarized beam

      To simulate an unpolarized beam or plane wave source, two simulations with orthogonal polarizations will be required.

      Hi. how to give unpolarized light to the simulation because i want to check whether there will be any polarization change  on metasurface. please help me

      Apologies for this, the content of this post got damaged for some reason. You can't model unpolarized light in FDTD directly. To simulate an unpolarized beam, you need 2 separate simulations, with 2 orthogonal polarizations (typically we use a polarization angle of 0 and 90°). Then you can average incoherently the results.

      You will find more information in this page.
