In order to calculate S-matrix for TE and TM polarizations, the example simply selects symmetric and anti-symmetric boundary conditions on z min bc. In the provided example, the waveguide is a strip waveguide and I sort of understand why this work. In my case, I am using a rib waveguide which is not symmetric across z-axis. How would I for the EME solver to select TE or TM modes separately in order to extract s-matrix from the parameter sweep?<\/p>\n<p>MMI example. <\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/464\/XJ24HPBUIXCW.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/464\/XJ24HPBUIXCW.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-159196","topic","type-topic","status-closed","hentry","topic-tag-lumerical"],"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":["1477"],"_bbp_likes_count":["0"],"_bbp_subscription":["239534"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159196"],"_bbp_forum_id":["27833"],"_bbp_engagement":["14496","200644"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["181153"],"_bbp_last_active_id":["181153"],"_bbp_last_active_time":["2021-06-09 02:16:53"]},"test":"upaudelumich-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159196","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\/159196\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159196"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
