We do a lot of work looking for these cases, and have published some for
planar EM solvers. Some examples that work quite well for this are a
zero-thickness stripline, and a coupled zero-thickness stripline, for which
theoretically exact closed-form solutions exist.
We have an Excel spreadsheet that will compute the exact closed-form values
for Zo, coupling, Z-parameters and S-parameters at any frequency for a
user-defined stripline/material geometry (flat conductors, lossless
materials). You can reach this at:
We have a benchmarking document on our web site that may help, starting at:
There are a couple of things with exact solutions, and a number of "common
sense" tests as well--all relating to planar EM (2.5D) simulation.

Subject: [SI-LIST] : More Help
Hi folks! Thanks to all those responding to my question on board
geometries. It worked so well I now have another question to present.
I'm looking for 2D and 3D electrical modeling cases that can serve as
standards. That is, they have a closed form solution, or solvable through
conformal mapping, or have been solved by so many experts that the solution
can serve as a standard. The cases I am aware of are for two round wires, a
round wire above a plane, and round coaxial conductors for 2D. I'm not
aware of anything for 3D (looking for plane and trace inductance with two
ports or more).
Again, any help is appreciated.
