do you see 15-20dB in IL and RL? If so, then I think the material parameters
are somehow different. Or is the difference just in the coupling?
In general, different Tools use different methods, but they should not have
such enormus difference, but different tools also allow different errors when
setting up the simulation. You will always get an answer to the chosen
simulation setup. How close the setup is to reality is user dependent.
I havn't used SIwave, but I know that HFSS sometimes has problems to get PCB
traces calculated correctly. This kind of simulation needs special care. I
prefer CST for 3D PBC simulations.

Hi all
I've simulated two coupled parallel microstrip lines with both HFSS and
SIwave(from
Ansoft), there is good agreement between the SHAPE of Scattering Matrix results
in two
softwares,BUT in the LEVEL of them there is about 15 - 20 dB difference,what do
you
think about this?
Regards
