Wikipedia:Articles for deletion/Fourier expansion electromagnetic field
The formulas are notable some sense and probably easy to give precise references for.  It seems like a lot of it is almost too trivial, though, and so I do worry about .  Anyone capable of reading the article is probably just as capable of coming up with these formulas on their own with a little effort.  Still, I don't really see that as a compelling reason to delete it
