Re: NEC-LIST: PCB transmission line modeling

Well, calling it by that name will bring about great confusion in the word
of numerical electromagnetics, especially with TLM proposed by Johns and
Beurle (1971). Maybe, just maybe you can call it (pause), an application
for layered or stratified PUL .

Hi there,

I have been using our own MoM code for such kind of modelling. At that
time we had
no Greens function for layered media and modelling features via
filamentary current
(triangular base pointmatching) and triangular patches (Rao Wilton
Glisson).

Patches are typically more involved and less suited for greater
structures but may
be used to get insight into individual behaviours.
The modelling of the tranmission lines was done by matching radius of
the wires
and dielectric constant of the MoM model to the PUL parameters of the
transmission line.
