RF Simulation Software
(OP)
Hello!
Does anyone know of any RF Simulation Software that allows for investigation of the effects on the human body and allows discrete components to be used?
Thanks!

RE: RF Simulation Software
Just last week, I attended a one-day introductory session on the subject of RF Safety. I was surprised to see that this field of study is very immature - lots of really dumb ideas and obvious mistakes.
I did see some slides showing NEC models of human heads being exposed to RF and the predicted heating effects. The NEC models of heads are fairly complex and require a lot of computational horsepower.
It seems that the use of human phantom models (dummies filled with various liquids) is quite common.
Here is a pre-canned Google search:

I suspect that you'll have to use something like Spice to predict the performanc of your discrete components and then link those results into NEC.
RE: RF Simulation Software
what kind of discrete components would you like to include in your 3D calculation.
If you are only interested in passive devices (R,L, C and maybe diodes) CST Microwave Studio could handle this directly.
For active components, you would have to split the simulation in two parts. One for the 3D simulation in which you replace the active elements by ports. You could then use the generated results (S-Parameter) in a circuit simulator.
Hope this helps,

Frank: We'd be using mostly passive devices. I'll look into CST Microwave Studio. Thanks!
