To be able to simulate even-odd mode effects, you'll have to model the
conductors as a system of coupled transmission lines. There are not many
simulators that can do it, and even the ones that can are pretty limited to the
number of conductors they can handle. Many of them can only handle lumped
models, where what you really need to see what's going on is a true distributed
model. You'll need a field solver to extract the coupled transmission line
matrices - it's not easily done analytically. Take a look at Ansoft, Applied
Simulation Technology, and Pacific Numerix. HSPICE can model coupled lines
using geometric input (conductor size, spacing, etc.), but I can't vouch for its
accuracy.
