The difference among XFDTD SEMCAD and Empire?

What about the CST?

Dear Caseywp,

They are based on FDTD but there are some differences of course: implementation of different FDTD (conformal, ADI), new acceleration techniques, visualization, handling capabilities of complex structures, postpro parameters, data handling, measurement interfaces, etc.

I used CST and SEMCAD X personally. I know XFDTD too. My vote is for SEMCAD X for my applications. You may evaluate yourself. I know that SEMCAD X provides full version of their software for limited time.

Best wishes,
