To restrict the simulation window, I choose to use rotated eme ports (port 3 and port 4). The theta angle of port 3\/4 is -45\/+45 deg. However, the calculated eigenmode for port 3&amp;4 isn&#8217;t a mode for a WG cross section of 1um x 400nm (please see the image below). How can I resolve this bug?
