[Getdp] Horn or waveguide antenna example/help

[Christophe Geuzaine]

Hi Paul,

We don't have ready-made examples for horn antenna, but this would indeed be interesting. As you point out, the missing ingredient is the imposition of more realistic boundary conditions (modal boundary conditions) - not just for horn antennas but for other types of waveguides as well.

I've opened an issue in our gitlab to keep track of the progress on this: https://gitlab.onelab.info/getdp/getdp/-/issues/68

There are no such examples so I really could do with some help with this.  I'm guessing it would be a combination of the straight waveguide and microstrip antenna models.
