TE is the light propagating in the Y direction, and TM is the light propagating in the X direction.<\/p>\n<p>I tried using random diple and specifying teh diple type as an electric dipole for Tm, and magnetic dipole for TE, but end up that the band structure I got is mixed, and no real difference between when I used magnetic or electric dipole. I also tried to change the angle of the (theta) in the dipole cloud, but I got the same thing. The boundary condition I used was Bloch for x, and y, and Z is PML.<\/p>\n<p>This is what I want to see, TE and TM are denoted by solid and dashed curves:<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/511\/JRIN44AN0UML.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/511\/JRIN44AN0UML.png\" alt=\"Untitled111.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-167870","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["960"],"_bbp_likes_count":["1"],"_bbp_subscription":["241475","291105"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["167870"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","241475","291105"],"_bbp_voice_count":["3"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["304728"],"_bbp_last_active_id":["304728"],"_bbp_last_active_time":["2023-09-04 04:00:29"]},"test":"sughra-mohameduef-fi"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/167870","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\/167870\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=167870"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
