Uh... maybe because they're different?

When I was working my way to engineering I was a senior associate
engineer working with a PhD who had tired of the politics in the
university environment, given up his tenure, and come to work for
Hughes. We were putting together a bench top setup to evaluate
something or the other in the mixers from the early version of the
Phoenix missile. The front end of this thing, from the waveguide slot
planar antenna back the the mixer inputs, was all waveguide.

Whatever we were doing required the use of a "magic" T. I, the ever
inquisitive student, asked; "Doc, how does a magic T work?"

Doc, former professor and the author of "Intermediate Mathematics of
Electromagnetics", replied,

"It's magic."
