many things has changed since pozar's publication... but the comparision and actually its way is quite intersting.
I can say and honestly i can say that ie3d is really good choice even if you consider cst or ansoft products.
are you sure that finite gnd (patch on layer 0) doesn't need -1 port to be connected?
i'll check simulation results tomorrow :> but thanks for this remark :)

:)
the only misunderstanding was that i assumed finite gnd and infinite will absorb similar ammount of time/memory :)
thinking about that again anyone would find this radiculous :>
anyway - ie3d is really helpful
I have to say tha I was really amazed by the analysys speed however if i use finite gnd simulation time is similar to other em simulators :<
for example analysys of cbcpw (simple wavegiuding structure) takes 5sec if backing groundplane is infinite and takes 50 sec if backing gnd is finite :<
I...
thanks for your help - i've found manually how to proceed symetrical optimalization :)
and i have to admit that ie3d is really flexible software especially coz this is only 2.5D simulator :>
thanks again and have a good day all of you!

shame on me :)
it's true that ports don't need gnd and can be differential... however i can't find anything about your second suggestion in manual... i've checked the website and found interactive movie about optimalization - nothing about symmetry though :|

I encountered a problem using zeland ie3d:
1. coplanar waveguide - ie3d need gnd when defining ports...
2. if i need to optimize strip width is there any chance to make optimalizatiom symmetrical so the gaps remain the same size?

genesys eagleware
Hi!
I have to test genesys eagleware accuracy in intermodulation analysis thus i'm looking for finished and working projects that i could use as an examples. Can you help, any of you?

My tee junction should operate at 12GHz with bandwidth as good as possible, S11 must be less than -20dB and of course it is 3dB power divider.
BTW it is microstrip sandwich structure.

rf tee junction
I have to make a broadband tee junction however i encounter several problms tweakinng my idea of project. Not only did I use czebyshew transformer but also I was trying to increase bandwith by increasing number of transformer sections. Till now with a tiny sucess.
I was...
thx a lot for your hint about John Wiley & Sons
however paper can't be the same because authors are C. S. Teoh, L. E. Davis once (W&S and this is what i need) and next Davis and Xie in attached paper.
If you have access to download full text i'll appreciate attachment :)
