But in my simulation file (geometry) it shows drastic change of gamma_dipole vs. wavelength plot (data from dipole TB box), as you can see in below attached figure, why ? and which one will be correct one?<\/p>\n<p><\/p>\n<\/p>\n<p>My file here <a href=\"https:\/\/drive.google.com\/drive\/folders\/1XIa6hxfUyNbkpw_ss1NZiwxxSFGSnasd?usp=sharing\" rel=\"nofollow\">https:\/\/drive.google.com\/drive\/folders\/1XIa6hxfUyNbkpw_ss1NZiwxxSFGSnasd?usp=sharing<\/a><\/p>\n<p><\/p>\n<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/744\/GU7W1K8ODRLM.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/744\/GU7W1K8ODRLM.png\" alt=\"Purcell factor.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-161692","topic","type-topic","status-closed","hentry"],"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":["807"],"_bbp_likes_count":["0"],"_bbp_subscription":["234853"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["161692"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","190664"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["190201"],"_bbp_last_active_id":["190201"],"_bbp_last_active_time":["2021-08-30 23:14:43"]},"test":"loqm"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/161692","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\/161692\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=161692"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
