Inconsistent results between Terminal Wave Port and Terminal Lumped Port when simulating a flat FCC cable ... can someone help me ?

[rdpdo2002]

Hello,

I would like to simulate the system {connector1 + 24 inches cable + connector2}, something like this :

Obviously, I cannot simulate this because of the computing cost....


But under HFSS, I can use deembedinbg using wave ports (but not using lumped ports) so my idea is to simulate :
- the S-parameters of the connector1 inputs / output
- a little length of cable using wave ports
- dembed to get the 24 inches lenght of cable
- the S-parameters of the connector2 inputs / output (which are the same as connector1)
- Add all the circuits in series

I am just wondering if I can add the S-parameters circuits in series and if it is correct to add them to get the total system s-parameters ?

Thanks you for your advice

is PET Er= 3.4 ?
