But, for some particular value of period or size of nanoparticle, the simulation diverged or the autosutoff level was oscillating.<\/p>\n<p>I decided to change the boundary condition with PML and still using the symmetry. <\/p>\n<p>However, I am having some issues to calculate the reflected power by a specific grating order, it differs very much with the total power reflected. In the following picture R stands for the total power reflected and R_Gn for the power reflected at the order 0.<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/332\/Q01M0KWYVU88.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/332\/Q01M0KWYVU88.png\" alt=\"R_1NP_period750_PML.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-164701","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["199"],"_bbp_likes_count":["0"],"_bbp_subscription":["255490"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164701"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","230290"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["199941"],"_bbp_last_active_id":["199941"],"_bbp_last_active_time":["2021-12-08 23:52:35"]},"test":"marius-crouzierc2n-upsaclay-fr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164701","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\/164701\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164701"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
