Third RF autograd notebook in the series! The first two notebooks were focused on box geometries. This third one demonstrates a coaxially fed patch antenna with a polyslab geometry.

There's still one piece to sort out with the meshing. The optimization is a little smoother if I use the full mesh override instead of the layer specs, but it costs more simulation credits. This still gets to a good result, but has a couple of noisy spots in the optimization. Wanted to post for now while I figure out which meshing strategy we want to go with (open to suggestions!)
