Check with Polar.
They manufacture TDRs and they have an excellent field solver for designing
the board construction.

Subject: [TN] controlled impedance
TechNetters, can anyone assist me with understanding controlled impedance
measurements on unpopulated PCBs? I have looked at TM-650, method 2.5.5.7.
If anyone with experience in making controlled impedance measurements could
contact me, I would appreciate it greatly.
