Given the necessity for a fine mesh due to the thinness of the monolayer, FDTD simulations are excessively time-consuming. Thus, I aimed to expedite the process by employing RCWA. However, I&#8217;ve encountered significant disparities in the results. While the overall trends appear similar, there&#8217;s a notable discrepancy in the peak positions, even after increasing the k vector in RCWA simulations. Could anyone offer insights or suggestions on additional steps I could take to align the results more accurately?<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/13-03-2024-1710289083-mceclip1.png\"><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-356735","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["341193","33648","192317"],"_bbp_author_ip":["168.143.243.14"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["290"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["356735"],"_bbp_forum_id":["27833"],"_bbp_engagement":["33648","192317","341193"],"_bbp_voice_count":["3"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["361410"],"_bbp_last_active_id":["361410"],"_bbp_last_active_time":["2024-04-09 22:35:51"]},"test":"akkimcaltech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/356735","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\/356735\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=356735"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
