I think FDTD has two ways to do so (1) using the S parameter and (2) using the far field moniter\/polarisation ellipse analysis group. However, I couldn&#039;t get the right answer. I want to verify reciprocity.&nbsp; Thus, polarization states should match if light is incident from both directions. Also, from a far field monitor, diffracted modes should be the same.&nbsp; <\/p>\n<p>I also used a very famous example here in all the discussion <a href=\"https:\/\/support.lumerical.com\/hc\/en-us\/articles\/360034395234-Calculating-the-far-field-polarization-ellipse\" rel=\"nofollow\">https:\/\/support.lumerical.com\/hc\/en-us\/articles\/360034395234-Calculating-the-far-field-polarization-ellipse<\/a>\u3002 <\/p>\n<p>Also, can we compare the result to see the polarisation rotation from s parameter and polarisation ellipse? <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/727\/QE7BD84F7IX1.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/727\/QE7BD84F7IX1.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-165267","topic","type-topic","status-closed","hentry","topic-tag-far-field-moniter-2","topic-tag-metasurface-1","topic-tag-polarisation-2","topic-tag-s-parameter-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["468"],"_bbp_likes_count":["0"],"_bbp_subscription":["244868"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["165267"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","244868"],"_bbp_voice_count":["2"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["201832"],"_bbp_last_active_id":["201832"],"_bbp_last_active_time":["2022-01-05 20:15:38"]},"test":"chamoliciomp-ac-cn"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/165267","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/165267\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=165267"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
