I am using box of monitors with 6th monitor is deactivated as it is on the substrate. But, I know the top monitor should be placed at a distance of greater than or equal to half of the emission wavelength(From lumerical resources). For example in my simulations, it is around 1540nm wavelength, So, I have placed top monitor around 0.85um from the FDTD boundaries on the top. So, i would like to know this rule is applicable for side placement of side monitors from side FDTD boundaries. Please find the attached figures for the reference. I have tried different cases where the side monitors are 1) 1um from FDTD region, 2) in the FDTD region, 3) 2.5 um from FDTD boundaries. I got almost similar farfield patterns in the case with slight difference in the intensity values.<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/05\/22-05-2024-1716406507-mceclip2.png\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/05\/22-05-2024-1716406615-mceclip3.jpg\"><\/p>\n<p>Could you please suggest me further regarding this about how to validate the distance from the FDTD boundary regions for the side monitors as shown in the above pictures?<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-368138","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["338176","33648"],"_bbp_author_ip":["184.24.96.177"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["257"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["368138"],"_bbp_forum_id":["27833"],"_bbp_engagement":["33648","338176"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["368373"],"_bbp_last_active_id":["368373"],"_bbp_last_active_time":["2024-05-23 18:37:16"]},"test":"pnairalbany-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/368138","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\/368138\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=368138"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
