Lynne,
CST Microwave Studio and Ansoft HFSS can both handle the 3D full wave
simulations at these frequencies. To create spice-type models you will
need to convert s-parameters derived from these tools into passive
time-domain simulation models. There are several commercial tools on
the market that perform this function. I have validated Sigrity
Broadband Spice with CST Microwave Studio to 40 GHz. and 50 Gbps
signalling against measurement, with the end simulations being done in
HSpice.
