To achieve this, I set the figure of merits (FOMs) to 0.5 for each port and used two separate FOM monitors (fom1 and fom2) to track the power distribution. However, I consistently observe that the FOM at the bar port exceeds that at the cross port, leading to an imbalance.&lt;\/p&gt;&lt;p&gt;Could you advise on whether it&rsquo;s possible to introduce an additional FOM or constraint to minimize this mismatch? Any guidance on adjusting the optimization setup to achieve a more balanced output would be greatly appreciated.&lt;\/p&gt;&lt;p&gt;Thank you very much for your assistance.&lt;\/p&gt;&lt;p&gt;-Partha&lt;br&gt;&lt;br&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/01-11-2024-1730482427-fom plot.JPG\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/01-11-2024-1730482456-fom code portion.JPG\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-392441","topic","type-topic","status-publish","hentry","topic-tag-inverse-design-2","topic-tag-photonics","topic-tag-subwavelength-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["142.157.192.82"],"_btv_view_count":["287"],"_bbp_topic_status":["unanswered"],"_bbp_notification_enabled":["74013"],"_bbp_subscription":["2592","74013"],"_bbp_topic_id":["392441"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","74013"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["392855"],"_bbp_last_active_id":["392855"],"_bbp_last_active_time":["2024-11-05 18:30:31"]},"test":"2d55cc8877bc73dbdaabbcc27c671fe2dcfca9d0"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/392441","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\/392441\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=392441"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
