HFSS - Hemispherical Lens Simulation

Hello there,

I am attempting to simulate a hemispherical lens in HFSS at 2mm (150 GHz), but have very little idea of how to set up this simulation accurately and determine the beam-width of the lens.

Another problem is that the size of lens (10 mm diameter) is large compared to a wavelength, which will result in a large simulation time. So if anyone has any ideas on how to cut this down (e.g. symmetry boundaries), that would be great.

Any suggestions will be appreciated.

Thank you for your time,

hiii;

do you have any idea about simuoation of sillver lens in hfss
