You can&#8217;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&deg;). Then you can average incoherently the results.&lt;\/p&gt;&lt;p&gt;You will find more information in this <a href=\"https:\/\/optics.ansys.com\/hc\/en-us\/articles\/1500006149562\" target=\"_blank\" rel=\"noopener\">page<\/a>.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-310092","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/310092","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/310092\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=310092"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
