I am attempting to model a GRIN TFF based 3 port coupler in zemax non-seqential mode. When using comercially available GRIN lens ZMX files in sequential mode, propagation is sinusoidal as expected for GRIN propagation. When I export to non-sequential mode it seems GRIN lens is no longer; propagation is linear and now this cylindrical lens seems to have uniform index of refraction instead of radially varying index of refraction.
Additionally I hope to model a variety of TFFs. Any resources on these subjects would be apreciated.
