Are MEEP actually the right choice for this kind of problem (I think so!)? Do you know of any other project (OSS) that might be better suited to my problem? Or even technical articles that discuss this subject.
First, I should say that my own research deals with photonics, so traditional RF and microwave circuits are not my forte. My impression is that a lot of people doing circuit simulations use integral-equation methods like FastCap (http://www.rle.mit.edu/cpg/research_codes.htm), as they are much more efficient than FDTD for this purpose.
One limitation of Meep for your purpose is that it currently doesn't allow you to directly specify a material with a fixed conductivity; instead, you have to specify the frequency-dependent complex dielectric function. This can simulate a conductivity, but it is more complicated.
(At the infrared and optical frequencies I mostly work with, a frequency-independent conductivity is not especially useful because it is not an accurate model of the material response.)
Next, the various signal sources should be fine (square waves), but can we add passive components, such as capacitors to this whole simulation? And how can we handle signal termination? If I have an impedance for a pin, can I specify a "current-sink" for this?
Well, it's all just Maxwell's equations, right? A capacitor is just a specific geometry; e.g. Meep can certainly simulate two metallic plates.
I'm not exactly sure what you have in mind with the pins, however. Steven _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
