microstrip r l c g

Hi all:

Do you know any software/tool which can
calculate the RLCG per-unit-length parameter
for microstrip, except Ansoft Maxwell 2D?

The cross section of the microstrip may be
multi-layered. Such as

___ Metal
___ SiO2
___ Si
___ Ground

Thanks in advance

ie3d can generate the transmission line equivalent ckt. To get your thing done draw tr line of any length and then simulate it. In modua there is a option to calculate tr line equv ckt. I have never used that option though.
