Diffraction in RL-GO
__Hi everybody. I have a question about RL-GO solver in FEKO. There is a capability to account for diffraction. The question is: does FEKO account for diffraction in the raytracing phase or only during the phase of summation of Huygens sources fields. In other words for the case of 3 interaction is there R-D-R and D-R-R rays, or only R-R-D, where R- reflection, D- diffraction.

Dear Marat
Under the Solver Settings (on the Solve/Run tab) in CADFEKO you will find the High Frequency tab with settings for the RL-GO. There you will find an option to "Export ray file for post processing".
I would suggest that you set up a test model with this option enabled and then view the rays in POSTFEKO. If your test model is set up such that for example an R-D-R interaction should be possible, you would see from the displayed rays if Feko does in fact consider such interactions or not.
Kind regards,
Johan H

__Hello Johan. Thank's for your respond. I am interesting in capabilities of last version of FEKO. In my 2018 version there is no diffraction at all.
