I&#8217;m trying to simulate the transmission of the waveguide.<\/p>\n<p>Two mode sources (one is fundamental TE mode, and another one is fundamental TM mode) are enabled simultaneously in 3D FDTD simulation. The amplitude of TE source is always kept at 1, and the amplitude of TM mode souce is changed from 0, 1, 2, 3, etc. A &#8216;Frequency domain field and power&#8217; monitor is enabled at the end of the FDTD simulation region to record the data. The transmission of the waveguide is plotted by visualizing &#8216;T&#8217; of the monitor. The question is the transmission &#8216;T&#8217;&nbsp; is always normalized within the region &#8216;0-1&#8217;, so how the transmission is normalized or calculated when there are 2 sources and when the amplitude of one source increases?<\/p>\n<p>Thanks!<\/p>\n","protected":false},"template":"","class_list":["post-244411","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.192.164.18"],"_bbp_subscription":["270563","2592"],"_btv_view_count":["1210"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["244411"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","270563"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["244549"],"_bbp_last_active_id":["244549"],"_bbp_last_active_time":["2022-12-20 17:13:30"]},"test":"qz5u21soton-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/244411","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\/244411\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=244411"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
