I have conducted simulations on the transmission and reflection properties of the meta-atom, and the results somewhat aligns with those reported in the article. Both sets of results, from the article and my own simulations, have been included as attachments. Now, I aim to measure the quality factor of the transmission curve. To achieve this, I utilized a low Q-analysis group from the object library. After adjusting the position of the time monitor, I executed the analysis group. However, the Q-Factor obtained is significantly larger compared to the Q-Factor presented in the article. Q-Factor, from article is 290 whereas after running the analysis group, I am getting, Additionally, I will attach screenshots of the results after running the analysis group. (I get resonant dip at 1281nm as per Figure 2 but the low-Q Analysis group shows resonance at 1691nm and the Q factor is very large)<img decoding=\"async\" title=\"Setup script 2\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/03-04-2024-1712127422-Screenshot 2024-04-03 120251.png\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" title=\"Transmission and Reflection curve from my simulation\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/03-04-2024-1712124039-HQ1.png\" alt=\"\" width=\"468\" height=\"312\"> Act<img decoding=\"async\" title=\"Q-Factor results after running the analysis group\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/03-04-2024-1712126695-Screenshot 2024-04-03 120122.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-360195","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["23.206.193.154"],"_bbp_subscription":["302729","2592"],"_btv_view_count":["197"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["360195"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","302729"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["360384"],"_bbp_last_active_id":["360384"],"_bbp_last_active_time":["2024-04-03 22:24:12"]},"test":"ph23resch01002iith-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360195","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":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360195\/revisions"}],"predecessor-version":[{"id":360199,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/360195\/revisions\/360199"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=360195"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
