According to the results, the effective index of Mode 1 is calculated as 1.605514, with TE\/TM polarization fractions of 82.1% and 83.17%, respectively. Mode 2, on the other hand, has reached cutoff and does not propagate. I am uncertain about the correct naming for Mode 1&mdash;would it be appropriate to label this mode as <strong>TM00<\/strong>? Could you please clarify the correct mode designation? Additionally, I would appreciate any explanation regarding the TE polarization fraction and the waveguide TE\/TM fraction.&nbsp;&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;Huriye<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/25-10-2024-1729847048-mceclip0.jpg\" \/>&lt;\/span&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-391353","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["295289","2592","473055"],"_bbp_author_ip":["194.27.125.188"],"_btv_view_count":["498"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["391353"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","295289","473055"],"_bbp_voice_count":["3"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["432909"],"_bbp_last_active_id":["432909"],"_bbp_last_active_time":["2025-05-29 22:29:21"],"_bbp_status":["publish"]},"test":"512105003ogr-uludag-edu-tr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/391353","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\/391353\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=391353"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
