When using FDTD I extract the phase by placing a point monitor far away from the structure (above the plane wave source) where I have a propagating plane wave. However, in the case of RCWA, I never have a propagating plane wave above the structure. It looks like that in RCWA, I have a standing wave above the resonant structure (in reflection).&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;What would be an appropriate method to extract the phase of the reflected light in RCWA? And, in general, how can I extract the complex reflection amplitude in RCWA.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Thank you!&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-388880","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["192317","2592"],"_bbp_author_ip":["131.215.220.163"],"_btv_view_count":["435"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["388880"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","192317"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["390920"],"_bbp_last_active_id":["390920"],"_bbp_last_active_time":["2024-10-22 18:33:26"]},"test":"sokhoyancaltech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/388880","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\/388880\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=388880"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
