To account for temperature changes, I added thermal modifier equations for relative permittivity and dielectric loss tangent, but the results aren&rsquo;t linear. I think the equations might be incorrect. I would like to know the correct thermal modifier equations for dielectrics like FR-4 and PTFE, thank you.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/02-10-2024-1727858113-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-387782","topic","type-topic","status-publish","hentry","topic-tag-AnsysSiwave-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["462815","109997"],"_bbp_author_ip":["117.16.132.173"],"_btv_view_count":["153"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["387782"],"_bbp_forum_id":["27793"],"_bbp_engagement":["109997","462815"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["389193"],"_bbp_last_active_id":["389193"],"_bbp_last_active_time":["2024-10-11 01:41:54"]},"test":"jhyeon1008mju-ac-kr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/387782","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\/387782\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=387782"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
