Hi,

I am very new to COMSOL I was wondering how you would model a coaxial probe in concrete sample and see the wave propagation through the concrete?

Thanks a lot!

1. By probe- I guess you mean the center conductor is protruding into concrete? Attach a drawing to make clear what you are doing.

2. If the wave propagation is in concrete- you need a model for permittivity and losses in concrete- you will need to find that in the literature because I don't think COMSOL knows the electrical properties of concrete.
