As the next step, I plan to fill the voids with a liquid crystal (LC), which is a birefringent material, and then create a cell composed of several different layers. Based on the guidance provided on your website, achieving reliable results requires a homogeneous environment. How should I approach the combination of a birefringent material and a non-homogeneous environment in my simulations? I have attached the relevant explanation and the link from Ansys website for reference.&lt;br&gt;https:\/\/optics.ansys.com\/hc\/en-us\/articles\/360042088813-Diffraction-grating&lt;br&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/08-01-2025-1736329962-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-404076","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27784"],"_bbp_topic_id":["404076"],"_bbp_subscription":["498497","473055","503797"],"_bbp_author_ip":["132.64.56.240"],"_bbp_last_reply_id":["404166"],"_bbp_last_active_id":["404166"],"_bbp_last_active_time":["2025-01-08 18:49:25"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["1"],"_bbp_voice_count":["2"],"_btv_view_count":["105"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1736345517:473055"],"_bbp_notification_enabled":["473055"],"_bbp_engagement":["473055","498497"]},"test":"adi-schlesingermail-huji-ac-il"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/404076","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\/404076\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=404076"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
