Thanks for the clarification. I don&rsquo;t think you will be able to do that with FDE. FDE just calculates the eigenmodes of a waveguide at a given cross-section. Then you can calculate the far-field projection of each of these modes. For the interference, I believe you would have to propagate the modes a certain distance to see the fringes. This can be done in other solvers like FDTD. But let me double check with my colleagues and get back to you.&lt;\/p&gt;&lt;p&gt;Regards,&lt;br&gt;Amrita&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-356695","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/356695","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/356695\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=356695"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
