I had been trying to calculate bending loss for a silicon waveguide. Initially, I tried with FEEM (the discussion is in the link: \/forum\/forums\/topic\/loss-vs-waveguide-bend-radius-in-lumerical-feem\/).<\/p>\n

Currently, I am trying to compare the results with that of the one obtained with EME. <\/p>\n

 I have followed the instruction in this post (\/forum\/forums\/topic\/is-it-possible-to-simulate-bent-waveguide-using-eme\/) to check the bending loss using EME. I found that the loss for the same bend radius keeping varying with change in span of simulation region. <\/p>\n

The bending loss for 15 mm bent radius, as obtained from FEEM was 50 dB\/cm, whereas EME gives different values as shown (for same settings, but different simulation region span).<\/p>\n

\"\"<\/p>\n

Here, 44.7 dB\/cm is the value obtained, which has been reduced to 7.8 dB\/cm for a larger simulation span.<\/p>\n

\"\"<\/p>\n

How much span should I keep while performing EME simulation? Please suggest what can be done.<\/p>\n

Thank you.<\/p>\n
