I have the electric field profiles at the xy and xz planes and now want to analyze the polarization of the field at the focal plane. How should I go about this? While searching, I found that plotting the vector field on top of the contour plot of the electric field in the xy plane could be useful. I came across the quiver function in MATLAB for plotting the vector fields. After exporting the electric field data at the xy plane to MATLAB and using the quiver function, I did not obtain the expected results.<\/p>\n<p>Can you please tell me how to determine the polarization of the field at the focal plane using Lumerical FDTD?<\/p>\n<p>Thanks in advance.<\/p>\n","protected":false},"template":"","class_list":["post-374337","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["302729","2592"],"_bbp_author_ip":["103.232.241.237"]," _bbp_last_reply_id":["0"],"_btv_view_count":["271"]," _bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["374337"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","302729"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["374782"],"_bbp_last_active_id":["374782"],"_bbp_last_active_time":["2024-08-01 20:26:48"]},"test":"ph23resch01002iith-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/374337","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\/374337\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=374337"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
