*Incident Wave (Magnitute: Gaussian Beam, Phase: Plane Wave)

Hi,
I have a problem with my HFSS simulation.
I have to simulate a measurement using The Incidence Wave which has the Gaussian Magnitude but Plane Wave Phase.
in other words, we will have the plane wane transfer in the air but its magnitude is as Gaussian beam..

I really hope to receive help and advice from everyone.
I really appreciate.

Thanks

hi

did you solve this problem somehow? I'm working on the similiar case and all the advice is good for me. If you would not have any sample project?
