FreeLists / si-list / [SI-LIST] characteristic impedance for embedded differential microstrip line

["Haikun Zhu" <haikun@xxxxxxxxx>]

Hi folks,

Can anyone point me to good resources for calculating the
characteristic impedance of embedded, edge coupled differential
microstrip line?

ADS linecalc has typical differential microstrip lines but they're not
embedded. I also found UCCALC from ultracad but it's not free. I'm now
trying to do it in Momentum. But if there is readily available
resources i'd be happy to know.

Thanks a lot,
Haikun
