FreeLists / si-list / [SI-LIST] Question on ADS Momentum simulation

[JP <edpc108@xxxxxxxxx>]

Hello Siers,

  when I simulated PowerGround_prj example that comes
along with ADS installation 2002c using momentum 3D
field solver, surprisingly Iam seeing at some points
S11 is greater than 1 in magnitude. In db it goes up
to +0.3db. 

How is this possible for a passive power planes? Is it
anything to do with numerical stability of simulation
algorithms?  

(since I took the standard ADS example, Iam assuming
that all substrate definations and other settings are
correct)

Thanks and regards,
Jayaprakash.
