Especially in a bent waveguide, where you see radiation in the direction opposite to the bend. I will recommend running a sweep for different values of the simulation span. It is hard to tell if we can trust any of the two results, until we perform a more systematic convergence testing. When you run a sweep, you will see that the after a certain point (simulation span), the losses become almost constant (converge) even when you increase the simulation region. Then you can use the point where the losses start converging as your final simulation region.&lt;\/p&gt;&lt;p&gt;Regards,&lt;br&gt;Amrita&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-368550","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi Anjali,As you might have already read, the modes can interact with the PML Boundaries to create artificial loss\/gain.
