Didn't the maintainer of QUCS publicly throw in the towel a few years ago? If I recall correctly, he more or less rage quit after people were using his work to design some pretty advanced RF stuff for sale, but weren't able to pay him to develop some more advanced simulation capabilities. He's posted a few cryptic comments saying that he's built support for full EM transverse mode simulation but won't release it publicly.
